Expert Solution
Step 1

Draw the Axial Loading diagram and the twisting moment diagram for the given shaft.

Mechanical Engineering homework question answer, step 1, image 1

Step 2

Understand that at the periphery of the of section a-a on the shaft there will normal axial stresses along the axis of the shaft and maximum torsional shear stress on the cross section of the shaft in the direction tangent to the twisting moment.

Write the expression for the compressive normal stress at the point.
