6-85 A shaft that is transmitting 240 hp at 1800 rpm must also support an axial tensile load of 20 kip. If the maximum tensile stress in the shaft is not to exceed 15 ksi, determine the minimum diameter required for the shaft.

A shaft is required to transmit 245 kW power at 240 rpm. The maximum torque may be 1.5 times the mean torque. The shear stress in the shaft should not exceed 40 N/mm^2 and the twist 1° per meter length. Determine the diameter required if a) The shaft is solid b) The shaft is hollow with external diameter twice the internal diameter.
