This problem describes an experimental method for determining the moment of inertia of an irregular shaped object such as the payload for a satellite. a counter weight of mass m, is suspended by a cord wound around a spool of radius r, forming part of a turntable supporting the object. the turntable can rotate w/o friction. when the counterweight is released from rest it descends through a distance h, acquiring a speed v. show that the moment of inertia i of the rotating apparatus is mr2 (2gh/v2 – 1).
