Question

The solid steel rotating shaft in the figure is supported at B and C, and is driven by a gear, not seen, which is linked to spur gear D which has a pitch diameter of 150 mm. The drive gear force F acts at a pressure angle of 20 degrees. The shaft transmits a torque to point A of Ta-350 N.m. The properties of machined steel shaft are Sy-420 MPa and Sut-560MPa. Use a safety factor of 2.5 and determine the minimum allowable diameter in section B and C. Assume sharp felt radii at the bearing shoulders to estimate the stress concentration factors.Explain.
