Car Safety Features Essay

As automobiles and other motor vehicles give faster, they force more and more dangerous to use. speckle this is the case, thither atomic number 18 m any incompatible methods that manufacturers have used to help block harm to their consumers. These methods include air get along outs, seatbelts, antilock happy chance systems and many more. These troika features be by far the al near commonly know rubber eraser features for simple machines, and pretty much any new simple machine that is manufactured leave behind have all three of these guard duty features, not only because of the interest in containing drivers safe but akinwise the recently huge appeal to gumshoe features and ratings for cars.Seat Belts Seat belts be by far the most common safety feature among cars. E veryone knows what they are, been taught to always buckle up, they muffle the risk of death by nearly 50%, and is illegal to not be wearing one while locomotion in a car. But barely do seatbelts do? Seat belts value drivers and passengers by strapping them into their seat. This foresees violent jerks caused by either collisions or sudden stops. The staple fibre idea of seatbelts is that they stop you from flying kayoed of the windshield of your car.Why would this happen? It happens because of something called inertia. inactivity matters tendency to keep mournful if its contemptible or keep staying still if its staying still, until it becomes low the influence of a force. Kind of like if you wake up in the aurora felling tired, you want to go concealment to eternal sleep until you force yourself to wake up. This is how inertia works. If you were travel in a car at 60 kilometres per hour, inertia would mean that the car, and everything deep shore it, would want to keep moving at 60 kilometres per hour.If the car decelerates very quickly, by chance due to a crock up, everything inside the car will still be moving at 60 kilometres per hour, but the car will be slo wing down very quickly. If you were not wearing a seatbelt, you would travel forwards at 60 kilometres per hour and crash through your windshield. Since windshields are do of thick glass, crashing into it would very easily kill you at a focal ratio like this. If you were wearing a seatbelt in a situation like this, the seatbelt acts as a force to stop you from moving forwards, greatly reducing the impact of the inertia.The most commonly know kind of seatbelt is known as the three-point seatbelt, which tramp be seen on the right. The three-point seatbelt is almost always used in cars and buses. The three-point seatbelt works by having a publicize of fabric not only crosswise your hip, but also across your social unit torso. The seatbelt has three points, two of them being make into the car, and the third point being where the seatbelt locks in, wherefore the name three-point seatbelt. Air Bags Another very common form of passenger testimonial is the air bag. Air bags are ba sically just what theyre called.They are bags and get filled with air during a crash, preventing the driver/passenger from hitting their transport onto the dashboard. practically like seat belts, they strive to decline the impact of inertia to prevent injury, by stopping the passengers head from moving forward. Air bags have three components that work in unison to business correctly the crash sensor, the inflator, and the air bag itself. The crash sensor is a whirl that detects the force that is equal to or great than driving into a brick wall at 16 to 24 kilometres per hour. If this force is met, the crash sensor sends a command to the inflator.The inflator tbiddy attains a reaction surrounded by sodium azide (NaN3) and potassium nitrate (KNO3) to create nitrogen attack (NO3). The inflator forces this gas into the airbag, cause the bag to inflate. The bag is made of a thin nylon fabric, which is folded into a compartment in both the steering wheel and the the dashboard, an d most of the time the seat or door. Anti-lock Braking dodging (ABS) Many accidents are cause by brakes being applies too much, fix up the wheels and cause the car to skid. ABS tries to prevent the wheel from locking up and reservation the car lose control. at that place are 4 components to ABS systems hurrying sensors, the pump, valves and the ascendence. The speed sensors furnish information to the controller of what speed the car is travelling at, they are usually fixed at the wheels. There is a valve in each of the brakes controlled by the ABS. There are three different positions that the valves can be in the valve being open, obturate the break line and releasing instancy form the brakes. Since valves release the pressure from the brakes, there needs to be something that puts the pressure tail in.Thats there the pump come in. When a valve reduces the pressure in the brakes, the pumps are there to put the pressure back in the brake system. And finally, there is the con troller. The controller is a computer placed somewhere in the car. The controller just controls how the speed sensors, the pumps and the valve operate. ABS works by detecting hen brakes are applied to hard, and begins to playing period the brakes on and off by taking away and re-applying the pressure on them. This stops the wheels on the cars from locking up, and most of the time stops the car from skidding.
