Question:

If the disk in Fig. 17-19 rolls without slipping, show that when moments are summed about the instantaneous center of zero velocity, IC, it is possible to use the moment equation ∑M_IC = l_Ic_α, where I_IC represents the moment of inertia of the disk calculated about the instantaneous axis of zero velocity.
