Essay On Crumple Zones
Crumple zones are one of the greatest innovations made with cars to protect the passengers in the event of an auto accident. Crumple zones cause impulse, or the change in momentum when an object acts on by a force for a certain amount of time. Though first, we need to know why crumple zones were made. An average of almost 1.3 million people die from nearly 5.5 million car accidents around the world annually. Along with this 20-50 million people are either injured or disabled in the wrecks. This is a big problem because of not only the loss of life, but the accidents cost about $518 billion USD globally per year. Innovators and automobile engineers/developers have noticed this issue and know that they need to find a new way to save these

According to his first law of motion, commonly known as the law of inertia, says an object in motion will stay in motion unless acted upon by another opposing force. For example, if a car is traveling 70 mph and hits a wall and stops right away the bodies will keep traveling forward at the same speed and once the bodies stop the organs continue going forward at the same speed too and slam against each other. That's where the inventions of seat belts, air bags and crumple zones come in. Seat belts hold the body pack so it doesn't go through the windshield or onto the dashboard. Though it only stops the middle and lower body while the human's head is still going forward. Now air bags come in and though they can be very effective, they also can be extremely dangerous if they go off at the wrong time. Air bags going off just a tad late can still be inflating when the head is in reach of it and once the meet before the air bag is fully inflated this can cause serious injury, such as dislocated joints, broken bones and in some cases death. Now crumple zones, as mentioned before, they absorb energy and if they work correctly, they can prevent most of the energy from reaching the occupants, causing the bodies to not have as much energy going forward, decreasing chance of injury or
