Disk B weighs 56 lb and has a centroidal radius of gyration of 12.5 in. The power unit C consists of a motor M and a disk A, which is driven at a constant angular speed of 1750 rev/min. The coefficients of static and kinetic friction between the two disks are μ = 0.75 and pk = 0.53, respectively. Disk B is initially stationary when contact with disk A is established by application of the constant force P = 3.5 lb. Determine the angular acceleration a of B and the time t required for B to reach its steady-state speed. The angular acceleration is positive if counterclockwise, negative if clockwise. 39 TA= 13.2 in. TB = 15.0 in. Answers: i t = i rad/s² S
