Select a steel from Appendix C-4a and a rpm between 1250 and 2000 rpm for a 40-mm-diameter shaft transmitting 500 kW. Bending and axial loads are negligible. Assume t ... 0.2 Su for safety.
(a) What is the nominal shear stress at the surface?
(b) If a hollow shaft of inside diameter 0.8 times outside diameter is used, what outside diameter would be required to give the same outer surface stress?
(c) How do weights of the solid and hollow shafts compare?
