A shaft is to be fitted with a flanged coupling having 8 bolts on a circle of diameter 150 mm. The shaft may be subjected to either a direct tensile load of 400 kN or a twisting moment of 18 kN·m. If the maximum direct and shearing stresses permissible in the bolt material are 125 MPa and 55 MPa respectively. Find the minimum diameter of the bolt required. Assume that each bolt takes an equal share of the load or torque.
