2. Determine the diameter of a solid steel shaft that will transmit 150kW at a
speed of 3 revolutions per second. If the allowable shearing stress is 85MPA.
Also, determine the dimensions of a hollow steel shaft whose inside
diameter is three-fourths of its outside diameter for the same conditions.
What is the ratio of the angles of twist per unit length for these two shafts?
