Question

4. (5 points) The cold-drawn AISI 1040 steel bar ( Sut = 590 MPa, Sy = 490 MPa ) shown in the figure is subjected to an axial load fluctuating between 12 kN to 28 kN. Estimate the fatigue factor of safety based on achieving infinite life and the yielding factor of safety. Use the Modified Goodman, Gerber, and ASME-elliptic criteria and compare their predictions. 6-mm D. 25 mm 10 mm

Step 1

Given: - Minimum load, \( F_{\text{min}} = 12 \, \text{kN} \) - Maximum load, \( F_{\text{max}} = 28 \, \text{kN} \) Mean load, \( F_m = \frac{F_{\text{max}} + F_{\text{min}}}{2} = \frac{28 + 12}{2} = 20 \, \text{kN} \) Alternating load, \( F_a = Show more…
