The stepped shaft shown in the figure is required to transmit 600 kW of power at 400 rpm. The shaft has a full quarter-circular fillet, and the smaller diameter D1= 100 mm. If the allowable shear stress at the stress concentration is 100 MPa, at what diameter will this stress be reached? Is this diameter an upper or a lower limit on the value of D2?

A hollow shaft transmits 9 MW at 300 rev/min. It is supposed that the maximum allowable stress is not to exceed 70 MN/m2 nor the angle of twist 0.5 degree per metre length of shafting. If the outside diameter of the shaft is 400 mm find the minimum thickness of the hollow shaft to satisfy the above conditions. G = 80 GN/m2. *
Determine the minimum diameter that can be used for a solid circular steel shaft which is limited to an allowable shear stress of 70 MPa and a maximum angle of twist of 1.5o (degrees) per meter length. Applied maximum torque is 25 KN-m and the overall shaft length is 1.25 meters. Shear modulus = G= 80 GPa Note: When using torsion stress formulas, you must convert the angle of twist from degrees to radians.
A solid steel shaft ABCDE turns freely in bearings at points A and E. The shaft is driven by the gear at C,which applies a torque T2 = 325lb−ft.
