3. The cold-drawn AISI 1040 steel bar shown in the figure is subjected to a
completely reversed axial load fluctuating between 28 kN in compression to 28 kN
in tension. Estimate the fatigue factor of safety based on achieving infinite life (using
Goodman line) and the yielding factor of safety. If infinite life is not predicted,
estimate the number of cycles to failure.
