Question:
You are given two objects and a ramp. Explain how you could measure the ratio of the moments of inertia of the two objects. Assume the two objects are both round (so that both roll), have the same mass and radius, and are solid (no holes in the center, etc.). Consider only objects that meet these criteria and with the shapes in Table 8.2. Both objects can roll without slipping down the ramp, and you have the equipment needed to measure the speeds of the objects as they roll.
