The shaft in Fig. Q4 is made with a safety factor of 2.5 and has an allowable shear stress of 50 MPa. The bearing at A and D exert only y and z components of forces on the shaft. a) Find the allowable stress. b) Determine the maximum torsion moment acting on the system. c) Draw bending moment diagram for the system. d) Determine the bending moment at B and C. [3 marks] [4 marks] [8 marks] [6 marks] e) Use maximum shear stress theory of failure to find the diameter of the shaft.
