\(5(25\%)\) A tension member in a machine is filleted as shown. The member has a manufacturing defect that causes the fluctuating tension load to be applied eccentrically resulting in a fluctuating bending stress as well. I have done all of the stress calculations for you including the stress concentration, and the resulting mean Von Mises stress is 65.1 MPa and the resulting Von Mises alternating stress is 25.1 MPa . The member is machined, and its dimensions are \(\mathrm{D}=33\mathrm{~mm},\mathrm{~d}=25\mathrm{~mm},\mathrm{~h}=3\mathrm{~mm}\) and \(\mathrm{r}=3\mathrm{~mm}\). The material has an ultimate strength \(\mathrm{Sut}^{2}=380\mathrm{MPa}\). Determine the infinte-life fatigue safety factor for the member for \(90\%\) reliability. Draw the Modified Goodman diagram and show the stress state. Label everything.
