Question

A motor delivers 275 hp at 1000 rpm to the end of a shaft (see figure). The gears at B and Ctake out 125 and 150 hp, respectively.
Determine the required diameter d of the shaft if the allowable shear stress is 7500 psi and the angle of twist between the motor and gear C is limited to 1.5°. (Assume G = 11.5 × 106 psi, L1 = 6 ft, and L2 = 4ft)
