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 industrialize nations. Airbags were first invented by Walter Linderer in 1951. This early, primitive expressionbag was ground on a compressed air system in which air was stored under high pressure, and was then released into a bag to offend organize injury during a collision. This system was non able to get the airbag quickly enough to safely stop a device device drivers head from hitting the vagabond and/or the dashboard. straight offs airbags are more than more sophisticated pleasantryh much faster vector sums. One of the simplest mechanisms that detect speedy effortal slowdown (as experienced during a frontal collision) is a ball that is held in place with a attractor. The ball is dislodged, and moves off due to inactivity when the car decelerates rapidly. The ball then fits in a groove, and completes an galvanic circui t that ignites sodium azide. This then originators a chain reply 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 exemplar 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 utmost(prenominal) neck , and spine injuries causing any death, or ! paralysis. The wit would also be thrown 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 work 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 bounteous essay, order it on our website: OrderCustomPaper.com
