Both pulleys are fixed to the shaft and as the shaft turns with constant angular velocity, the power of pulley A is transmitted to pulley B. Determine the horizontal tension T in the belt on pulley B and the x, y, z components ofreaction at the journal bearing C and thrust bearing D if θ = 45°. The bearings are in proper alignment and exert only force reactions on the shaft.
