Over 37, 000 people die in car crashes each year, which is on average 3,287 deaths a day. (Road Crash Statistics) 20-50 million people are injured or disabled and about two million of those injured suffer permanent injuries. (CNN) It is proven that the most common injuries are neck injuries including whiplash, sudden movement of head and neck which causes neck muscles and ligaments damage, and vocal cord paralysis. Chest injuries are also quite heard, for example broken ribs, collapsed lungs and traumatic cardiac arrest: however, the most serious ones are head injuries such as concussions, comas and traumatic brain injuries and back injuries that comprehend nerve damage caused by damage to the spinal cord, reduced control over arms, hands, legs, feet and other body parts and some patients can be left permanently paralyzed. (Find Law) 38% of car crashes is due to mobile phones. Followed by, 30% of car accidents occurred by an excess of speed. The second most common is caused by drinking, in fact over the past decade, drunk driving has reached nearly 113, 000 deaths. Those are the top 3 sources of car accidents.
(After Car Accidents) ‘Unless action is taken, road traffic injuries are predicted to become the fifth leading cause of death by 2030.’ (World Health Organization) Airbags are passive detains which are designed to activate automatically when an automobile gets into a crash. In the United States new vehicles have to incorporate dual front airbags.
(Life Wire) 8,000 thousands lives were saved by airbags between 1991 and 2001. (NHTSA) Airbags can only be used once and after an accident new ones should be included in the vehicle again. Airbags are made out of three parts: the air bag, the inflator, and the propellant. ‘The airbag is sewn from a woven nylon fabric and can come in different shapes and sizes depending on specific vehicle requirements.
‘ (Made How) Airbags are able to minimize the impact on people. Airbags extend time to slow down the change in momentum of the driver. When people suffer from a car collision they tend to move according to Newton’s first law of Inertia. The driver’s motion carries him to the windshield. This will happen over a short amount of time and a large force (F) in order to stop the driver’s momentum.
F=m?t. If instead there is an airbag in front on the driver, the time duration of the impact is increased (??t) as the force is decreased. f= m?TAirbags also have vents which are used when you hit it hard, some air expels to reduce the force and increase time.
