ut 1.60 in- Section A - A y [3]. A rotating steel shaft loaded by a force F varying from 0 to 50 kN is shown in the figure below. The shaft material properties are S =800 N/mm and S = 600 N/mm and the shaft is machined. Determine the diameter of shaft based on Goodman line, for a factor of safety of 1.5 and 90% reliability. All dimensions in the figure are in mm.
