The two outer disks are identical, each with mass M: 61 g, radius R = 2.9 cm, and moment of inertia UZMRZ. The central, smaller disk has mass M2 and radius R12. 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 = 0.425 N. The tension in the string is not sufcient 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 ? tabletop. In Case 2 the string is pulled horizontally, parallel to the tabletop. In both cases the yoyo rolls without slipping. 25% Part (a) What is the moment of inertia Icy about the central axis (i.e. the axis perpendicular to the circular face) of the yoyo, in kg.m-.
