A 15-mm diameter steel bolt passes through two rigid plates, each 25 mm thick. The screw thread has a pitch of 1 mm. Determine (a) the direct stress induced in the bolt if the nut is tightened by one fifteenth of a turn; and (b) the average shear stress in the bolt head assuming shearing on a cylindrical surface of the same diameter as the bolt (E = 200 GPa).
