Draw the free body diagram of the link PQR and the link SQT

Draw the free body diagram of the link PQR, and the link SQT Find the forces and moment across the cut at a - a. Over the section a - a, compute and show the distribution of transverse shear stress, bending stress, axial stress, and torsional shear stress At point B, compute magnitude and orientation of maximum shear stress, maximum principal stress, and orientation of maximum principal stress.

Solution

Transverse shear stress is 145mpa.

Bending stress is 67mpa.

Axial stress is 40mpa.

Torsional stress is 220mpa.
