A beam of circular cross-section has a length of 5m and is simply supported at its ends. It is required to carry a total load of 57 kN uniformly distributed over the whole length. If the maximum bending stress is not to exceed 13 MPa and the maximum deflection is limited to 4 cm, the diameter of shaft in mm is given by : (take E= 18 GPa.)
