Required information

The cold

-

drawn AISI

1040

steel bar shown in the figure is subjected to a completely reversed axial load fluctuating between

22

kN in compression to

22

kN in tension. Estimate the fatigue factor of safety based on achieving infinite life and the yielding factor of safety. If infinite life is not predicted, estimate the number of cycles to failure.

What is the factor of safety against fatigue?
