Question

Q2)- A hollow steel shaft of 400 mm external diameter transmits 9 MW at 120 rev/min. If the angle of twist measured over a length of 2 m is 0.450 and G is 80 GN/m2, estimate the internal diameter of the shaft, the maximum shearing stress and the strain energy per metre length of shaft. Find the diameter of the solid shaft which will transmit the same power at the same maximum stress and find the ratio of the strain energy per metre length in this shaft to that in the hollow shaft.
