A steel bolt 25 mm diameter and 400 mm long is surrounded by a copper sleave of 30 mm internal diameter 35 mm external diameter of the same length. The assembly is now rigidly fixed at both ends by washers of negligible length. If pitch of the thread is 1.5 mm and one of the nut is tightened through 60°, calculate the stresses developed in the copper sleeve and steel bolt. Take ES = 200 GPa and EC = 100 GPa.
