The rotating shaft shown in the figure is machined from AISI 1020 CD steel. It is subjected to a force of F=6 kN.
Problem 4: The rotating shaft shown in the figure is machined from AISI 1020 CD steel. It is subjected to a force of F=6 kN. Find the maximum factor of safety for fatigue based on infinite life. If the life is not infinite, estimate the number of cycles. Be sure to check for yielding. All dimensions are in mm.

A strip 300 mm wide and 25 mm thick is rolled to a final thickness of 21 mm with ∅500 mm rolls running at 60 RPM. K = 275 MPa and n=0.2. Using two passes of draft = 2 mm (i.e. t1=23 mm and t2=21 mm) , the class found that the rolling forces were 936 and 1220 kN respectively, and that the power requirement was 171 kW (based on the 2nd pass). It is hypothesized that since the flow...
