A crankshaft supported by bearings at A and B is subjected to a horizontal force P = 4 kN at point C, and a torque T at its right end is in static equilibrium (Figure P1.7). Find:
a. The value of the torque T and the reactions at supports
b. The shear force, moment, and torque acting on the cross section at D Given: a = 120mm, b = 50mm, d = 70mm, P = 4 kN.
