A space frame strut has a rectangular cross section of 10.0 mm by 30.0 mm that is made from 1040 cold drawn steel. It sees a load that varies from a tensile force of 20.0 kN to a compressive force of 8.0 kN. If the part needs to have a reliability factor of 99%, what is the design factor using the Goodman Method? Use the larger dimension (30.0 mm) for the size factor in this problem.

Please solve fully and write clearly
Il): A 25 inches long hot rolled AISI 1025 steel rod is to be subjected to an alternating bending load that will vary from a -5000 lb to +7200 lb as shown in Fig. 1. The properties of this material are given as: the ultimate tensile stress σ,-75,000 psi, the yield stress σ,-48,000 psi. Assume a theoretical stress concentration factor of K-1.65 and the notch sensitivity for this material is q-0.88. The safety factor...
