The solid cylindrical rotor weighs 64.4 lb and is mounted in bearings A and B of the frame which rotates about the vertical Z-axis. If the rotor spins at the constant rate p = 50 rad/sec relative to the frame and if the frame itself rotates at the constant rate Ω = 30 rad/sec, compute the bending moment M in the shaft at C which the lower portion of the shaft exerts on the upper portion. Also compute the kinetic energy T of the rotor. Neglect the mass of the frame.
