1. A 2-in-diameter steel shaft rotates at 240 rpm. If the shearing stress is limited to 12 ksi, determine the
maximum horsepower that can be transmitted.
2
A steel propeller shaft is to transmit 4.5 MW at 3 Hz without exceeding a shearing stress of 50 MPa or
twisting through more than 1* in a length of 26 diameters. Compute the proper diameter if G = 83 GPa

3.
A flexible shaft consists of a 0.20-in diameter steel wire encased in a stationary tube that fits closely
enough to impose a frictional torque of 0.50 lb in/in. Determine the maximum length of the shaft if the
shearing stress is not to exceed 20 ks. What will be the angular deformation of one end relative to the
other end? G12 x 106 psi.
