Question:

Solve Prob. 4.100 100 for θ = 90°. Problem 4.100: For the portion of a machine shown, the 100-mmdiameter pulley A and wheel B are fixed to a shaft supported by bearings at C and D. The spring of constant 366 N/m 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 masses of the shaft, pulley, and wheel
