Unformatted text preview: BC at time t starting from rest. Solve the problem assuming that (a) the disk is set in a smooth bearing at B so that it rotates with curvilinear translation, (b) the disk is fixed to the shaft BC , and (c) the disk is given an initial freely spinning angular velocity D k prior to application of the torque. 644...
