8.14 (B). Calculate the minimum diameter of a solid shaft which is required to transmit 70 kW at 600 rev/min if the shear stress is not to exceed 75 MN/m2. If a bending moment of 300 Nm is now applied to the shaft find the speed at which the shaft must be driven in order to transmit the same horsepower for the same value of maximum shear [630 rev/min.] stress.
