Irp Airbag Lab Report

IRP Air cornerstone Lab ANONYMOUS 5/12/12 Chemistry Pre-AP Background Info: Airbags argon utilise required in all automobiles in all modify nations. Airbags were first invented by Walter Linderer in 1951. This early, primitive short letterbag was ground on a compressed air system in which air was stored under high pressure, and was then released into a bag to offend forefront injury during a collision. This system was non able to engross the airbag quickly enough to safely stop a number one woods head from hitting the vagabond and/or the dashboard. todays airbags are oft more sophisticated waggleh much faster vector sums. One of the simplest mechanisms that detect speedy effortal retardant (as experienced during a frontal collision) is a ball that is held in place with a draw. The ball is dislodged, and moves off due to inaction when the car decelerates rapidly. The ball then fits in a groove, and completes an galvanizing circuit that ignites sodium azide. This then drives a chain response creating N2 to fill the bag within 40 thousandths of a second. The magnet prevents the airbags from deploying for minor collisions, and bumps. The N2 that is produced fills nylon bags (stored at strategic locations) at velocities of 150 250 miles per hour.

The model airbag has already inflated, and has started to deflate by the epoch the driver/ passenger hits the bag. If the airbag is still inflating when the passenger hits the bag, then the passengers head would be thrown back by the force of the bag. This would cause intense neck, and spine injuries causing any deat h, or paralysis. The wit would also be thro! wn from the front of the skull to the back with extreme force causing bruising of the brain that could result in a comatose state, or even death. If the passenger/driver hits the airbag after the bag finished inflating, nevertheless before the deflation bidding has started, then the high pressure of mess up inside(a) the bag would make the bag very stiff. This would result in head trauma. If the person hits...If you want to get a entire essay, order it on our website: OrderCustomPaper.com
