5-82. The shaft is made from a solid steel section A Band a tubular portion made of steel and having a brass core. If it is fixed to a rigid

support at A, and a torque ofT= 75 N m is applied to it at C, determine the angle of twist that occurs at C and compute the maximum shear stress and maximum shear strain in the brass and steel.Take G = 80 GPa, Gr= 40 GPa.%3D
