A hollow steel shaft of length 1.75 m transmits 2000 kW of power at a speed of150 rev/min. The inside diameter is to be 0.75 times the outside diameter. Themaximum allowable torsional shear stress for the steel is 130 MN/m2and themodulus of rigidity (G) for the steel is 83 GN/m2. Given that a factor of safety of2 is required for the shaft, determine:i) the torque acting on the shaft;ii) the required external and internal diameters for the shaft; iii) the torsional shear stress set-up in the shaft material at the inside surfaceof the hollow shaft, and sketch the stress distribution through the shaftwall;iv) the angle of twist (in degrees) due to the torque.
