How stylebags, Seatbelts and Crumple Zones OperateAir bags and seat belts buy the farm with the same model of providing a stopping rack to gain the clipping over which the occupier comes to a stop. The caprice of an heading is its ability to mystify damage, the higher(prenominal) the momentum the more damage it is practicable for it to cause. Momentum is deliberate by the command p=mv. When a simple machine collides with another(prenominal) object or stops abruptly it undergoes a limiting in its momentum, this is cognize as impulse and mountain be calculated by using the following formula ?p= Ft, we cannot practically transfigure the impulse or the world power use in a crash so instead we use up to extend the sentence over which the strike occurs. Since impulse is a aeonian value when we increase the sentence of the striking the bear on playacting on the object is and then decreased i.e. if you double the time that it takes for the object to stop you gravel halved the force apply to it. Air bags atomic number 18 triggered by accelerometers postured within the vehicle that leave behind cause them to inflate with nitrogen float in a collision at more than 6km/h. Seatbelts suffer the occupier in place and are as well jolly resilient so they depress the time over which the occupant comes to a stop.
Both also work alongside nitrogen?s First legality of Motion ?A bole in motion will continue at a constant velocity until it is acted upon by a force?. They picture a controlled stopping force so that the occupant of the car does not collide with herculean objects such as the splashboard or windscreen. Crumple zones mesh with a similar concept to seatbelts and airbags; they project to increase the time over which the collision occurs. These ripple zones are usually construct into...
