Elastic Band Race Car

Paper, Order, or Assignment Requirements

I need you to do the poster part of the attached assignment. The Diameter of the rear wheels is 8cm. You can just make up any estimated values for everything else. First we planned some ideas for the car. Then we picked the one we thought was best. We used CATIA to make a file that can be put in the laser cutter for the wheels to be made. In section 4 it asks for an A3 poster which gives
• Details of your testing of the elastic bands and the coefficient of friction • Detailed analysis from first principles of your vehicle’s performance. • Detailed design of your vehicle’s drive mechanism 
For this you can just make up any realistic values.
For the part about the drive mechanism, we pinned an elastic band to a stick that was parallel to the rear axle and then we wrapped the rubber band around the rear axle so that it would make the wheels spin.
In order to do the different parts of the race we changed how many times the rubber band was wrapped around the rear axle.
