tabletop. In Case 2 the string is pulled horizontally, parallel to the tabletop. In both cases the yoyo (18%) Problem 7: A yoyo is constructed by attaching three uniform, solid disks along their F central axes as shown. The two outer disks are identical, each with mass M = 5 7 g, radius R = 3.8 cm, and moment of inertia l/ZMRZ. The central, smaller disk has mass M2 and radius R/2. A light, exible string of negligible mass is wrapped counterclockwise around the central disk of the yoyo. The yoyo is then placed on a horizontal tabletop and the string is gently pulled with a constant force R F = 0.275 N. The tension in the string is not sufficient to cause the yoyo to leave the tabletop. In this problem consider the two cases show. In Case 1 the string is pulled straight up, perpendicular to the I R rolls without slipping. 2 F Ethccxperttaxom E (.7 25% Part (a) What is the moment of inertia [C M about the central axis (i.e. the axis perpendicular to the circular face) of the yoyo, in kg-mz. 10M: 8.74 * 10'5 10M: 8.74E-5 J Correct! E :9 25% Part (b) In both cases shown, what is the magnitude of the torque I exerted by the string about the contact point of the yoyo with the table, in N'm? r = 5.22 * 1
