3. An experiment is set up as shown in Figure Q3 to measure the moment of inertia of a circular flywheel. The mass of 30 kg is attached to a light inextensible string which is wrapped around the outer diameter of the flywheel which has a radius of 0.4 m. The mass is released when the system is at rest and drops 5.4 m in a time of 3 seconds. Friction in the bearings can be neglected Flywheel Bearing 30...
