a. The maximum design load on the component is Fmax=48kN. Determine the minimum cross-sectional area to meet the following design constraints simultaneously: i. The component must not yield. ii. The length of the component under load must not change by more than 0.10%. iii. The component must not fracture due to the presence of internal flaws as large as 1.0mm. b. After completing the quasi-static analysis of part a), you realize that the in-service loading is actually a fully-reversed cyclic load (+/- 48kN). i. Assuming that the design requirement is for infinite life ( 107cycles) and that no internal or external flaws exist, does the minimum required cross-sectional area need to be updated? ii. If the cyclic load was not fully reversed, but instead corresponded to R=0 conditions, does this change your calculation? Why
