oversized yo-yo is made from two identical solid disks each of mass M = 1.90 kg and radius R = 10.9 cm. The two disks are joined by a solid cylinder of radius r = 4.00 cm and mass = 1.00 kg as in the figure below. Take the center of the cylinder as the axis of the system, with positive torques directed to the left along this axis. All torques and angular variables are e calculated around this axis. Light string is wrapped around the cylinder, and the system is then allowed to drop from rest. %3D 00 R R M M (a) What is the moment of inertia of the system? Give a symbolic answer. (Use any variable or symbol stated above as necessary. Do not substitute numerical values; use variables only.) mr + 2MR (b) What torque does gravity exert on the system with respect to the given axis?
