Forces on falling mass m: mg - T - f = ma Torques on the disk-pulley system: Tr = Idisk a GGG Linear and angular acceleration: a = ar If one solves these equations for Idisk, the result is Idisk = mr2 2- 1 - (ma)] (8) that the conservation1. What is meant by "moment of inertia?" (4 pts) 2. Show how to obtain Equation (8) from Equations (5), (6), and (7) in Laboratory Manual. (6 pts) 3. The figure shows two disks, A and B, cemented together, rotating with angular acceleration a. The radius of the small disk B is 3/4 the radius of the larger disk. Calculate VA the ratio of the tangential velocity of a point on the rim of disk A to the tangential velocity of a point on the rim of disk B, -2. (5 pts) VB 4. For the two disks in problem 3, what is the ratio of the linear acceleration of a point on the rim of disk A to the linear acceleration of a point on the rim of disk B, 24? (5 pts)
