Determine the rate of change of the angular momentum HC of the disk of Prob. 18.5.

Prob. 18.5

A thin disk of mass m = 4 kg rotates at the constant rate ω2 = 15 rad/s with respect to arm ABC, which itself rotates at the constant rate ω 1 = 5 rad/s about the y axis. Determine the angular momentum of the disk about its center C.
