Today lets have a look on the auto show going in Geneva(Switzerland) from 7th to 17th of this month. The show is a renowned platform for automakers to showcase their latest offerings and is organised every year for which every car enthusiast eagerly waits..Let me tell you a little more about this show...

What is this Show??
The International Geneva Motor Show (French: Salon International de l'Auto) is an annual auto show held in March in the Swiss city of Geneva. The show is hosted at the Geneva Palexpo, a
The term Driver Information System is getting popular day by day as cars are advancing and so is the technology. The analog systems are being replaced by digital ones and at much cheaper cost. Driver Information System(DIS) is the system installed in a car which gathers all the necessary information useful to a driver from various sensory equipment and display them all together in a single display behind the steering wheel(in some cases somewhere on the dashboard. Have a look at the various information it provide..

What DIS Shows ???
Information shown in most of the DIS:
Indicates if any door of the car is open or not properly closed.
Indicators for any Battery, Fuel, Steering or Engine issues.
Outside Temperature and Current Time.
Distance traveled for a trip or Total Distance the car has traveled.
In the world of technology, everything is becoming more and more convenient. Let's take the case of controlling the temperature inside your beloved car. Gone are the days when you had to rotate the knobs and press a few buttons...welcome to the world of automatic..welcome to Automatic Climate Control...
Automatic Climate Control is a technology present in the cars which lets you set a specific temperature and set you free from changing the fan speed or turning the cooling or heating On and off. This technology lets you set a desired temperature and maintain that temperature throughout
Topic for today is rear windshield defogger which can be easily recognized in the rear windshield of a car as a pattern of multiple thin lines. As the name suggests this system works to remove the fog from the rear windshield of your vehicle when the outside atmosphere is very cold. I will tell you why this system is used and how it is used..So lets, start with why it is used...
Rear Windshield Defogger Button
Why Rear Windshield Defogger :
How do you feel if someone closes your eyes and ask you to walk?? Same feeling comes when a driver has to reverse a car with fog blocking the view. To prevent this from happening the cars are coming equipped with defogger in rear windshield, So that in case there's fog on the windshield you can remove it just by turning on the defogger.
Although there's a valid point that fog on the windows and front windshield gets removed just by turning on the Air Conditioner. This process is good but for rear windshield the thing either work too slow or in some cases doesn't work. For this reason a rear defogger is a must and it works quickly.

How does it works:
The mechanism used inside this system is just similar to the mechanism used in Heated Seats. A very basic mechanism in which there is a circuit with few wires and a resistance. The logic behind is that when the current is passed through the circuit the resistance opposes the flow of current through it and thus resistance generates heat. This heat is generated in the resistance which is present on the windshield in the form of wired pattern. As son as heat comes up the fog present near the pattern gets evaporated and we are left with a clear windshield for our ultimate driving experience.
Grid lines present in the rear defogger
Pros:
Quick
Very much needed in winters
Easy mechanism
Current flowing is very low so no chances of shock in case of touching.
Cons:
The wired pattern is very thin and can easily be chipped off if not taken care of.
Since it is electrical system problems can occur without notice.
Winter season is on and here is a useful automotive thing that makes your driving very comfortable in this cool weather...As many of you must have noticed that when there's chilling atmosphere outside and you enter your car, you find the seats very uncomfortable to sit as they are too cool to sit on..but the car manufacturers have this unique thing to make you happy....I am talking about Heated Seats...I'll discuss what is Heated Seats and how they work??
Heated Seats button in a car
Heated Seats:
Heated seats is the optional set of seats which are configured to heat up with a press of a button. These days it is common features of costly luxury cars. The seats are stuffed with electronic circuitry which develops heat and makes them hot enough to make your driving comfortable. The whole functioning is done with the help of a button present in the car. Many car owners opt for external heated configuration in the form of seat covers or customize their seats with some outside vendors. Now take a look on how it functions..
How Heated Seats Work ??
The functioning of Heated seats is done with the help of following materials:
Relay
Heating element
Thermostat
Connecting Wires
Inside of a Heated seat (Wired Network is heating Element)
The basic logic behind the heating mechanism is very simple. If you remember anything about current and resistance in physics then it is very easy for you. A current is passed through the heating element and heating element generates heat to make the seats warm. When a person switches on the button, the relay allows the current to flow through the heating element(which can be a wire and acts as resistance). As the current passes through the heating element, it resists the current from flowing through it which in turn generates heat and that what we need. This heat makes the seats hot and comfortable for winters. But there has to be some limit for the temperature as it may burn the fabric, for this reason the whole setup is connected to a thermostat which reads the temperature of heating element and disconnect the current supply as soon it reaches a preset limit. After sometime when the temperature of the seat lowers, the thermostat allows the current to flow through the circuit and that how temperature is maintained.
Few systems have setting for different ranges of temperature to suit your needs.
Pros and Cons:
As this is boon for all the drivers who wish for cozy seats in this winter season but since it is electrical configuration that's why it's bit risky. Although the car manufacturers make sure the the systems are fault proof and reliable for longer runs.

Today I am writing off after a week long gap because I was busy celebrating Diwali :)..I got a question from one of my friend about Automobile Tuning on my facebook page..So here I am with the information. I will tell about what this term means "Automobile Tuning" means. So lets start up with what is Automobile Tuning..
Automobile Engine tuning
What is Automobile Tuning:
Automobile tuning is nothing but a term given to the process of optimizing your automobile to give the best on road. It includes checking up the vital functioning of main components and changing up the ones worn out but the process doesn't end here. The whole tuning process is divided into three major sections as per the work involved in it. If you ever visited a car/bike workshop with an intention of getting it serviced, then you must be knowing that tuning is a part of your servicing. After servicing the workshop returns your vehicle with the performance it is made for. Now take a look at the types of Automobile Tuning.
Types of Tuning:
Well there are uncountable people living on earth and everyone may have a different perception about types of tuning but as far as I am concerned, I categorize them into three:
Engine Tuning
ECU Tuning
Performance Tuning
Now the engine and performance is known word but what's ECU?? Don't you worry I will take this up a bit later, first lets see what happens in Engine Tuning..
Engine Tuning:
Engine tuning involves the very basic things but important things to check primarily. I will tell them in bullet points with specifying why it's done, here are these:
Replace Engine oil : As due to regular usage the viscosity of engine oil decreases which in turn will increase friction in engine.
Replace Air Filter : The dust and other particles keeps settling on the filter part which needs to be replaced.
Replace Oil Filter : The worn out tiny particles from the engine gets clogged into the oil filter and may block the flow of oil inside.
Replace Spark Plugs: This part of your vehicle is necessary for igniting the engine and needs to be checks for any fault.
Replacing Timing Belt
Replace Belts: Belts are responsible for transferring power from engine to the axle and these need to be replaced periodically.
Fill Up Coolant: It keeps flowing to keep the engine cool and thus gets evaporated by a certain amount and hence needs to be filled back periodically.
Battery Check-Up: Adding distilled water into the battery and cleaning up the terminals.
Re-Fastening the Bolts: Due to engine vibrations the bolts get loose so a check is necessary.
And many more...
ECU Tuning:
First let me tell you whats ECU..it is Engine Control unit which takes care of all the specific tasks in engine. Although ECU thing is not very new but old automobiles were ECU free as the controls were analog not digital. But now every automobile has it be it a Car or a Bike.
ECU of a Car
ECU does so many tasks like Control of Air/Fuel Mixture, Ignition Timing, Variable Valve Timing and many more stuffs..These ECU's are coded by the companies with specific timings and settings to obtain a controlled output from the engine.
Few automobiles have programmable ECU's which can be programmed for various settings to achieve different performances. The company which manufactures ECU's also provides workshop guys a device that they can use for programming ECU's. Although these tasks are done only by experts as a minor change in setting can result in a major change.
Performance Tuning:
This type is tuning is exclusive as it is done as per the specific tasks to be done by the automobiles. This tuning makes sure that your machine gives its best performance even better than the company specified it to give. Suppose a bike is used for Motorsports then its obvious that all the major components should be able to withstand extra heat that would be burdened over them during high performance or for example take case of rally sport where the suspension used needs to be replaced with better sustainability which would have not been used otherwise. Performance tuning is not a regular process for regular automobiles but its done only where it is needed. Beside changing up the component, the timing and ratios are of great importance.
That's all I have to tell about the Automobile Tuning...share your views or suggestions with me..
The topic for today is Engine Oil, Its the liquid that the engine drinks. I will tell you about the Engine Oil , What it is, It's properties and other things about Engine oil. Lets start with whats Engine Oil:
Engine Oil
Engine Oil:
The basic requirement for any Engine to run is the oil which gives it the lubrication to perform the basic movement. Engine is made up of metallic parts which have a lot of friction and when the parts have to make any movement, the friction prevents the parts from doing so. The solution for this is a lubricant that decrease the friction and enhances the motion of the individual parts. The friction present between the parts convert the energy produced by engine into heat and Engine oil helps as an energy saver. Contact between moving surfaces also wears away those parts, which could lead to lower efficiency and degradation of the engine. Apart from lubricating the moving parts, the engine oil also serves as a protector from corrosion and also cleans the engine.
Engine Oil Working:
There are few engine parts involved in Oil Flow:
Oil Pump
Oil Filter
Oil Supply Vents
Engine oil flows through whole engine and lubricate every part internally. All Engine oil is present at the bottom of the internal combustion engine. The function of oil pump is to pump the oil from the bottom of the engine and then transfer it to flow through the Oil Supply Vents which are present as small vents on the connecting rods(see How Engine Works). The oil then fills up in the cylinders where pistons are moving. The Engine oil basically creates a thin layer of lubricant over the moving parts which prevents the direct contact between them at the time of movement. This Indirect contact reduces the friction. Even with such low friction, while in motion few minute particles of metals wears out from the engine parts and flow away with the oil. These waste particles are passed trapped inside the oil filter which is present in the path of flow of oil. The extra oil reaches to the bottom of the engine from where it is again pumped up and the cycle goes on until the engine stops.
Since the parts are covered up with this Engine oil the chances of parts getting corroded is highly reduced and the life of the parts increases.
It's Properties??
Most of the engine oils are made up of petroleum hydrocarbons derived from crude oil and few additives which makes these oils useful. A basic and important property of engine oil is viscosity. The viscosity of a liquid can be thought of as its "thickness" or a measure of its resistance to flow. The viscosity must be high enough to maintain a lubricating film, but low enough that the oil can flow around the engine parts under all conditions. The viscosity index is a measure of how much the oil's viscosity changes as temperature changes. A higher viscosity index indicates the viscosity changes less with temperature than a lower viscosity index.
Another property of the Engine oil is Flash Point, It's the lowest temperature at which the oil starts burning. Since the temperature inside the engine is very very high, the oil should have high flash point otherwise the engine will burn out :). That's why the companies performs a check for minute volatile particles in the oil made and removes them so as to increase the flash point.
There are other properties which the manufacturers add on to improvise their product among the competition.

Among all the automobiles cars are my favorite and their styling is the thing that i like the most. In this post I will tell you about the Daytime Running Lamp (DRL) which are the most stylish feature of a car and I personally like them the most. DRLs can be found on every costly cars nowadays be it an Audi or A Mercedes or A BMW or A Volkswagen. These Daytime running lamps add beauty to the front grille of the car which attracts the eyeballs of the viewers. Lets us now see what is DRL, Why it is used, What it is made up of???
A typical DRL
What is DRL??
I first saw these on an Audi roaming around in my neighborhood an year back. I was amazed to see the beauty these lights added to the car. But one thing I found bit weird that these lights were turned On even in daylight so became curious about the usage as normally a light is used to increase visibility in night time. I will let you know about the usage but let me tell you what is DRL.
Daytime running lamps is a strip like structure consisting of a series of LED's which emit bright light and these strips are paced at the both the corners of front bumpers.
DRL in Mercedes C-Class in Winter Daytime
A Designer DRl in Audi A4
Why it is Used??
Although If I am the owner of the car I don't mind these DRLs placed on my bumpers even if they don't have any use as they add the style factor but in this world nothing is done without a purpose.
Daytime running lamps are used to improve the visibility of an DRLs equipped car to other vehicles. This technology was introduced because in countries where the lighting conditions in winter daytime is bit dark, the vehicles have to either turn on dimmed headlamps or look for another alternative.
DRLs offer great visibility factor as the lights are bright and can be easily seen in low lighting conditions and there by reducing the accidental risks. Studies shows the after the introduction of Daytime running lamps the accidents in low lighting have decreased comparatively.

How they work??
LED Used in DRLs
The DRLs are made up of LED (Light Emitting Diode) which consume less energy and give bright lights. The LEDs are made up of semiconductor material like silicon which is abundant in nature. The DRLs present in the cars can be programmed to automatically turn on when the light is low. The sensors present in the car checks whether the light is optimum or is low, as soon as the outside light gets low the DRLs get automatically turned on. Although user have a choice to turn off the automatic mode and turn on the DRLs manually.
Benefits:
Safety: Other vehicles can see you quickly even in low light conditions.
Ease: As the DRLs get automatically switched on the driver can relax doing no added effort.
Fuel Consumption: As DRLs are made up of LEDs and power consumption of LED is very low and usage of headlights is reduced so there is a saving in fuel consumption.
Headlight Life: As the usage of headlights is diminished, their life is increased.
Style: For me this is the most important benefit of these DRLs :)
With this post I am highlighting the very basic part of an automobile, the Battery. Battery is the power house of an automobile, be it a car or a truck or a motorcycle. Batteries act as a power source for the vehicle, they provide power from sparking of the engine to lighting up the headlights. By this post you'll get to know what is a battery, what it is made of, and how it works. Lets have a look..
What is an automobile battery ??
A typical lead-acid automobile battery
First of all let's have a look at the technical definition of an automobile battery and it states that "An automobile battery is a type of rechargeable battery that supplies electric energy to an automobile." The sole purpose of the battery is igniting the engine so that the vehicle can start off and in addition to that the battery provides power to different parts of the car like stereo, headlamps, inner illumination etc.
What it is made of ??
Inside of an lead-acid battery
The most common type of batteries are lead-acid batteries where the lead part is the electrodes and the acid part is the electrolyte. The batteries contains a series of plates dipped inside the electrolyte which is Sulpuric Acid, you must have heard this name before in chemistry classes. There are partitions inside the battery which are called cells and the batteries are mostly defined by the no. of cells present in it. Most common ones used in automobiles are 6 cells batteries. Every battery has two terminals one is positive and another one is negative. Here in this case the negative terminal is formed by pure Lead plate and the positive one is formed lead oxide and these two terminals are present dipped inside the acid part which is sulphuric acid. each cell contains the positive and negative terminals and these series of six cells is covered up with the hard casing inside which the whole reaction takes place.
How it works ??
For this part you must scratch your mind and think about the chemistry part that you learnt in school. Think about ions, charge, current etc. Here are the equations involved:
The overall chemical reaction is:
At the negative terminal the charge and discharge reactions are:
At the positive terminal the charge and discharge reactions are:
Discharging:
Discharging a battery causes the formation of lead sulfate crystals (PbSO4) at both the negative and positive terminals, as well as the release of electrons (e-) due to the change in valence charge of the lead. The formation of this lead sulfate uses sulfate from the sulfuric acid (H2SO4) electrolyte surrounding the battery. As a result the electrolyte becomes less concentrated. Full discharge would result in both electrodes being covered with lead sulfate and water rather than sulfuric acid surrounding the electrodes. At full discharge the two electrodes are the same material, and there is no chemical potential or voltage between the two electrodes. In practice, however, discharging stops at the cutoff voltage, long before this point. The battery should not therefore be discharged below this voltage.
A amaron battery placed inside a car.
Charging:
The charging reaction converts the lead sulfate (PbSO4) at the negative electrode to lead. At the positive terminal the reaction converts the lead to lead oxide (PbO2) . As a by-product of this reaction, hydrogen is evolved. During the first part of the charging cycle, the conversion of lead sulfate to lead and lead oxide is the dominant reaction. However, as charging proceeds and most of the lead sulfate is converted to either lead or lead dioxide, the charging current electrolyzes the water from the electrolyte and both hydrogen and oxygen gas are evolved, a process known as the "gassing" of the battery. If current is being provided to the battery faster than lead sulfate can be converted, then gassing begins before all the lead sulfate is converted, that is, before the battery is fully charged.

This post of mine is about a technology that is a part of the higher end segment of automobiles, the technology is Keyless Entry which is realized with the help of Smart Key. Although this feature is mainly present in the costlier versions of automobiles but few car makers are introducing this feature in their lower segments. In this post we will discuss about what is keyless entry, how its done and what are its advantages.
What is Keyless Entry:
As the name suggests this technology gives the convenience to the car owners to move into their cars without actually inserting the key into it. Some of you might be thinking that i am talking about the central locking system that is present in the car, but you are wrong. Yes, keyless entry systems have remote just like the regular central locking remotes but here the difference is that the remote doesn't have a key attached to it. Now that's the reason why the technology is called keyless entry as there is no key present.
These days the remote present in these cars are called smart key as the remote is smart enough to recognize you and allow you to enter inside the car and do what you want. If you wonder that if there is no key then how the engine is going to start. For this read the next section Push Start /Stop button.
Keyless entry : A smart key from Nissan's Car
Push Start/Stop button:
For a keyless entry to be literally keyless the car should be equipped with such a technology that allows the owner of the car to start the engine without the key, for this the solution is push start/stop button.
Its a normal button present below the steering wheel near by the position where actually ignition keys are inserted. The sole purpose of this button is to start the engine if user presses it once and to turn off the engine when the user press it again. Its like a toggle switch with on/off functionality and thus eliminating the need of key to start. Shown below is a push start stop button present in the cars. In india the car which first introduced Push start stop function is Nissan's Micra.
Keyless Entry : Push Start Stop Button
How it works:
The keyless entry systems depend upon infrared signals to function. These signals are sent by the smart key (actually the remote) to the infrared receiver present in the car which receives the signals and check the signals if they are from the right smart key. The signals sent are encrypted so that nobody can tweak the signals in case of stealing. When the owner reaches near the car, the receiver matches the signals and unlock the car. The range of keyless entry is restricted to few inches and that's why the car unlocks only when the user is close enough to enter the car and preventing the car unlocking unnecessarily.
Now lets see how the Push Start Stop Button works. The button has a spark triggering mechanism which gets activated when the button is pushed for start. The spark burns the fuel and engine starts but there is a catch. The Start-stop button doesn't work without getting the signals from the smart key. Nobody can start engine just by sitting inside the car. The car checks the infrared signals and then only starts the engine thus increasing the security strength of the technology. The smart key sends a different code every time to improve security and integration.
It's Advantages:
You can enter and start driving without looking for key in your pocket.
The car cant be started without having the Smart Key and due to coded signals the security is add-on.
Easy locking and unlocking.
You have less chances of loosing it as you don't take it out.
And yes Style to flaunt :)

This post of mine is about a car accessory which you might not be aware of but its quite popular in the other side of world. The accessory is popularized as DASHCAM. Dashcams in the cars act as your third eye..which means it can see what you can't or would miss with those two eyes of yours.. In this post I will tell you what is Dashcam, why these are used, where these are used and what are its specifications...
What is a Dashcam??
Dashcam is the word made up by shortening of two words " Dashboard & Camera " which adds up to Dash-Cam. Dashcam is just another camera with varied specifications from different brands and customized to be suitable for your cars. The Dashcam is placed in the middle of the dashboard so that it can take the frontal footage of the events that is happening in the path ahead. Have a look at the image below to see what exactly it looks like...
A dashcam installed in a car
A type of Dashcam
Why dashcams are used??
The dashcams were first introduced by U.S. Law enforcement to capture the Chase events and the On-Road live criminal events. Although the videos taken by the Law enforcing vehicles were not accessible to the general public and were only used in the criminal proceedings. Sooner this accessory became a rage in the US as the public started liking the usage of these devices. These dashcams installed in the cars can actually capture a fraud event or it can capture the accidental mis-hapening to help out the users and the law agencies in some way .
You can actually have a proof if somebody hit your car and the fault was not yours in this case it behaves as your third eye. In another case these dashcams are loved by the storm chasers who can freely capture the nature's destruction without worrying about holding the cameras. So, you can wonder how differently these cams can be used. You can see these footage at your own convenient place just by transferring the data or you can delete the not needed data and clear off the memory.

A tornado captured by a dashcam
What are the specifications??
As its an accessory, in this ever evolving technology world the specifications keep on changing or you can say upgrading. There are few specifications which you should keep in mind for clarity and safe storage of your footage..Here are some of the few specifications to check before owning one:
Camera Resolution : Mega Pixels
Video Definition : Standard or High Definition (HD)
USB Interface to easy data transfer
External Memory Support : Just in case you run out of memory
Swivel Angle : Camera should be able to rotate at max to capture at varied angles.
Continuous Recording
Modes : Camera and Video recording
Memory Type : Disk Drives or Memory Cards
Capturing Memory Limit
The costlier the Dashcam is , more would be the specifications and features. But even a normal one would serve the purpose of capturing an event.

In this post I will discuss about the Exhaust System which many of you might not be interested in. But since you have started reading this , let me tell you the exhaust system is not that boring. In this post you will get to know why we need an exhaust system and how it functions in an automobile. So first let us know whats basically a Exhaust System...
Whats an Exhaust System:
Firstly, Let's digest the definition and it says that "An Exhaust system is usually piping used to guide reaction exhaust gases away from a controlled combustion inside an engine". The definition is quite understandable and the exhaust system is basically the pipes that you see at the lower back end of a car or in a bike. These pipes can be seen smoking out the hazardous gases from the engine which causes pollution. Now lets see why we need it and is it really necessary.
A Car Exhaust System
Why an Exhaust System:
The question arises to our mind that why we need this whole pipe structure, the gases can be easily passed out from a valve. The answer to this is that the gases that an engine emits out are so hazardous that it can make you sleep forever if inhaled directly, So a proper system is needed for these gases to be made less hazardous. The gases that comes out of the exhaust system are very much safer than the actual ones thanks to this Exhaust system. The other main advantage of these exhaust are that they reduce the noise that compressed engine gases make while coming out. These Exhaust give those gases much space to travel and thus the pressure of gases is reduced and so is the noise level.
How it Works:
A detailed Anatomy of a car exhaust system
Shown above is the detailed anatomy of the exhaust system. I'll start from the top where the flange is mentioned. Flange connects the exhaust system with the main engine from where all the gases are coming out. Coming from there the gases meet the catalytic converter where different chemical reactions occur to convert the highly toxic gases to the less toxic ones. Here the hazardous CO(carbon Mono oxide) gas is converted into less toxic CO2(carbon dioxide)..I'll not go into the chemical equations now. Also here the NO2 (Nitrogen Dioxide)gas is broken into Nitrogen and oxygen parts so that the gases which goes into atmosphere are less harmful.Then the gases comes into the middle chamber where the unburnt fuel particles are trapped into the perforated pipes and then in the end there's resonator which reduces the pressure of the gases further and thus reducing the noise caused.
In the end what we get is the gases which are cleaner for environment, although not as clean as they should be but at-least the system makes the gases less dangerous.
This is it about the exhaust system...will come up with some other interesting topic.

In this post of mine the automobile featured is the fighter jets and the topic for you is "How the fighter jets land on aircraft carriers ??? ". These machines are so fascinating that people of all age group love and respect them. Here I will tell you about the mechanism used by which these high speed fighter jets land in the short area runway of aircraft carrier. Before knowing the mechanism involved you guys need to know about three things:
Whats an Aircraft Carrier??
Whats Tail Hook??
Whats Arresting gear??
So first we will discuss What exactly is an Aircraft carrier:
Aircraft carriers are warships that are used as a seagoing carrier ship which acts as an portable airbase for the naval operations. It has a large top over which airbase is made having runway strips and fighter jets parked over. Have a look on the picture to understand:
A typical Aircraft Carrier
What exactly is Tail hook:
Its a landing accessory fitted at the rear end of the fighter jets which comes out at the time of landing. Its a fixed metal part flattened at the rear end to make it a claw like hook. It is mechanically pulled in/out through the aircraft. Have a look at the pic below.
A Tail Hook
What exactly is Arresting Gear:
Arresting gear consist of one or more steel cables (arresting cables) which are stretched from both the end of the runway where the fighter jet is going to land. These cables are controlled by the retractable holders which keep the wires stretchable to a certain limit. See the pic below:
Arresting cables
Why a mechanism is needed:
Although the fighter jets are capable enough to stop by themselves in normal conditions but when there is lack of space like in aircraft carriers, then the use of tail-hook and arresting gear comes into picture. Since the space is less and speed is high, the jets are force fully stopped onto the carrier.
How its done:
When a fighter jet is landing on the carrier the pilot lowers down the Tail-hook of the jet and that tailhook touches the surface of the carrier and comes into contact with the arresting gear. When arresting gear get hold of the tailhook, all the inertia of the jet gets transferred to the cables and the resistance from the cables stop the aircraft at shorter distance.
However sometimes the tailhook miss out the arresting gear and the this case of failure is know as "Boltered". To prevent the process to be boltered two three arresting gear are placed one after the another so that if the tailhook misses first stretched cable then there's a possibility that it come in contact with the other cables following.
A landing in action
What if the Tailhook gets faulty:
In that case the jet has a bad luck. For this case the the jets are diverted to some nearby runways or if there's some limitations then the aircraft can be halted by erecting net barricades in its path. But this approach is least used as the tailhook and arresting gears are checked prior to the landings. Have a look at the Barricaded Instance.
A barricade for emergency landing
This is it about how fighter jets land on the aircraft carriers..Read other interesting posts on the blog.

The tires which don't have a tube in it are called TubeLess tires. The definition is very easy but the technology behind making these wheels has replaced the conventional tube tires. Nowadays almost all the vehicles are equipped with these tires as an standard equipment.
What's the Difference:
A tubeless tire cutout to show you the interiors
The major difference between tube and tubeless tires as I discussed is the Tube which is not present in the tube-less ones as obvious. Another difference is that the tire and the rim makes a non-leaking air compartment and the valve is fitted directly to rim unlike in tube tires where the valve is fitted onto the tube.
Below is the comparison between the tube and tubeless tires.
Comparison among the tires
Advantages:
More resistant to puncture as the construction is robust.
Sustain the air for longer duration.
Doesn't cause instability when the air pressure is low.
Increase efficiency as friction between tire and tube is eliminated.
Easy to remove punctures as there is no need to take out the whole tube to fix it.
How the puncture is fixed:
The tools used for fixing the puncture are reduced in numbers and size as there is no need to take out the whole to fix the puncture. Nowadays fixing a puncture is not a tedious job and even you can fix the puncture with the help of a fixing kit.
Shown below is a puncture fixing kit for tubeless tires which is all you need.
First the tire is checked for any nail or other sharp object then the tire is drilled down at that point with a tool shown below. Then a fixing strip is coated with the adhesive solution and then with the help of the tool, the strip is pierced deep within. That's It!!!
Take out the tool out leaving behind the strip inside the tire and you are ready to go...
