QUESTION 2: 2.1 A shaft is to transmit 190 kW at 180 rev/min. If the maximum torque transmitted is 50% more than the mean torque, the shear stress should not exceed 45 MPa nor an angle of twist of greater than 1.2° per metre length. Determine the required diameter if: 2.1.1 The shaft is solid 2.1.2 The shaft is hollow with the ratio of inner to outer diameters of 3:5. Take modulus of rigidity=80 GPa.
