Just was going to see if anyone had any ideas for this project that's due like wedsday.
Objective: Build a wheeled deivce that will coast down a ramp and brake to a stop in a prescribed area.
Permitted materials: Wheels must be made from standard music or computer CD's
The device must have at least three wheels which are attached to one or more axles. The wheels must rotate but the framework cannot rotate. The axels may or may not rotate. The wheels can be cut,drilled,glued together,ect. Only the wheels may touch the ramp and floor. No remote controls allowed the device must be self contained. No energy sources allowed(batteries,pre wound springs..ect.)
The car will roll down a 4ft long 16in high ramp then coast for 3ft on a level surface and after that it needs to stop quickly in order to get a good score...
If anyone has any ideas pls help lol...So far we have four wheels attached to threaded bolts as axles drilled into a piece of wood. The idea is as the wheels roll they will turn down the threads and hit the body creating friction that will hopefully stop the car, but we doubt it will have enough force to stop it. HELP!
