A 1.134-kg disk of radius 100 mm is attached to the yoke BCD by means of short shafts fitted in bearings at B and D. The 0.68-kg yoke has a radius of gyration of 75 mm about the x axis. Initially the assembly is rotating at 120 rpm with the disk in the plane of the yoke (θ = 0). If the disk is slightly disturbed and rotates with respect to the yoke until θ =90?, where it is stopped by a small bar at D, determine the final angular velocity of the assembly.
