Two discs rotate freely about their vertical axis passing through their centers in the horizontal plane. The corresponding moments of inertia are I1 and I2 with angular velocities w1 and w2. The upper disc falls on the lower one, and after short time they both spin at the same steady – state angular velocity (due to friction). Find: a. The steady – state angular velocity of both discs. b. . The work done by the frictional forces during the process.
