Question
A hollow steel shaft of length 1.75 m transmits 2000 kW of power at a speed of
150 rev/min. The inside diameter is to be 0.75 times the outside diameter. The
maximum allowable torsional shear stress for the steel is 130 MN/m2
and the
modulus of rigidity (G) for the steel is 83 GN/m2
. Given that a factor of safety of
2 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 surface
of the hollow shaft, and sketch the stress distribution through the shaft
wall;
iv) the angle of twist (in degrees) due to the torque.
