A cylindrical 1045 steel bar is subjected to repeated compre

A cylindrical 1045 steel bar is subjected to repeated compression- tension stress cycling along its axis. The fatigue limit stress amplitude for this alloy it 310 MPa. If the load amplitude is 22.000 N. compute the minimum allowable bar diameter to ensure that fatigue failure will not occur. Assume a factor of safety of 2.0. 12.5 mm 20mm 13.4mm 15mm None of the above Insufficient information

Solution

5. Insufficient information
