The Pasco rotational motion apparatus is used to measure the moment of inertia for a ring. The step pulley diameter is 3.60 centimeter. The inner diameter of the ring is 11.321 centimeter while the other diameter is 13.598 centimeter. The mass of the ring is measured to be 731.2 gram. Determine the moment of inertia.
