A hollow shaft is to transmit 20 kW at 300 rpm. The loading is such that a maximum bending moment of 1000 Nm is induced in the shaft, together with an additional axial thrust of 15 kN. The shaft is supported on bearings 1500 mm apart. The values of shock and fatigue factors in torsion and bending (Kt and Kb) are 1.25 and 1.75 respectively. The inside diameter is 0.8 times the outside diameter. Determine the outer diameter of the...
