[edit] Crash Cars Project 2008

---

[edit] Background Information

Year after year automakers have made faster cars capable of transporting more people from place to place. In the 1940’s, 50’s, and 60’s automobiles were “made to last” with rigid frames, bulky bodies made of thick sheet metal. They had metal dashboards, big steering wheels, with steel columns in the center and no seat belts! These cars survived crash fairly well, unfortunately the same cannot be said for the passengers. Starting as early as the 1950’s, automotive engineers began to design cars to protect passengers in automobile accidents. Seat belts, 5 m.p.h. bumpers, and lightweight materials were introduced. A radical idea began to develop, sacrifice the vehicle in order to protect the passenger. Indianapolis 500 cars are designed to disintegrate in crashes. Each part that separates from the main chassis of the race car takes a part of the impact that the vehicle was experiencing. Drivers walked away from 150+ M.P.H. crashes because of this. Modern passenger cars advertise such things as “crumple zones” that protect passengers in crashes. They are called crumples zones because the ends of the today’s lighter weight automobiles are designed to fold and wrinkle on impact, extending the time of the duration of the crash.

[edit] Project Objective

Students are charged with the task of designing and producing an automobile body that will protect an egg from a head on collision with a wall. Students may use any material that they wish to produce their vehicle, as long as it posses no threat to their safety, or thesafety of other people. The body must meet the given specifications and limitations.
