5-82. The shaft is made from a solid steel section AB and a tubular portion made of steel and having a brass core. If it is fixed to a rigid support at A, and a torque of T = 75 Nm 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 Gst=80 GPa, Gbr = 40 GPa. 12 mm 0.6 m B T = 75 Nm 25 mm C 0.9 m A 5-82. The shaft is made from a solid steel section AB and a tubular portion made of steel and having a brass core.
