Figure Q1 shows a solid steel shaft AF which is supported by frictionless bearings at B and F. It is coupled to an electric motor at A. The modulus of rigidity of steel shaft is 75 GPa. The shaft is loaded by the torque as stated in the figure below. Answer the following:
(a) Sketch the free body diagram and calculate the internal torque acting in each section of the shaft.

(b) Calculate the maximum shear stress in the shaft.

(c) Determine the total angle of twist between F and A.
