Question: For the portion of a machine shown, the 4-in.-diameter pulley A and wheel B are fixed to a shaft supported by bearings at C and

For the portion of a machine shown, the 4-in.-diameter pulley A and wheel B are fixed to a shaft supported by bearings at C and D. The spring of constant 2 lb/in. is unstretched when θ = 0, and the bearing at C does not exert any axial force. Knowing that θ = 180° and that the machine is at rest and in equilibrium, determine

(a) The tension T,

(b) The reactions at C and D. Neglect the weights of the shaft, pulley, and wheel.
