Question

A solid steel shaft (G = 83 GPa) have been limited to an angular deformation of 1.83° and a torsional shearing stress of 60 MPa. The solid steel shaft has a length of 1.5 m. If a hollow steel shaft with an outside diameter of 150 mm and having the same length is used to replace the solid steel shaft, calculate (a) the inside diameter of the hollow steel shaft by preserving the same mass (b) the inside diameter of the hollow steel shaft by preserving the strength and the torsional shearing stress.
