Question

Center of Mass Start Center of Mass

Your company, DynaRace, has been hired as consultant to a Soapbox derby team. The car and driver have a maximum mass Mmax and the wheel maximum radius is Rmax . Your job is to advise them on the following issue: a) Heavy wheel and light body, b) Light wheel and heavy body. Assume the wheels are considered as homogeneous disks and 2 g ms = 9.81 / , h m =10

1) Plot the velocity of the car as a function of the ratio r = m_wheel/M_max. Use practical values of r

2) Advise the team on their choice

3) Wheel Mass Moment of Inertia

4) Work Done as the Car Rolls Down the hill

5) Kinetic Energy as the car Rolls Down the hill

6) Velocity of the Car as it rolls Down the Hill

7) Velocity of the Car at the Bottom of the Hill

Then write a MATLAB program to plot the graph of Velocity vs. ratio. Where r = m_wheel/M_max^.
