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. T 2.2 A compound steel shaft is formed by attaching a solid and a hollow shaft as shown in below figure. The maximum allowable shear stress in the shaft should not exceed 70 MPa and the total angle of twist should not exceed 2.08°. If the length x is 2.28 m and the length y is 1.69 m, calculate for a value of G-83 GPa: 2.2.1 The magnitude of the allowable maximum torque 2.2.2 The angle of twist of the hollow shaft. 2.2.3 The stiffness of each shaft. 100 mm X 70 mm 70 mm y €
