Can you solve 7B.3 please

68 73.2 (10 points) A non-cold-worked cylindrical rod with an initial length of 800 mm and diameter of 15 mm is to be deformed using a tensile load of 45 kN. Of the materials listed below, which are possible candidates if you assume that failure of the system occurs when the rod plastically deforms? Do the possible candidates change if you change your assumption to the system failing at the onset of necking in the rod? Justify your choice(s). Material Young's Modulus (GPa) Yield Strength (MPa) UTS (MPa) Elongation (%) 1040 Steel 205 440 680 25 Brass 100 185 310 Copper 125 160 220 44 73.3 (14 points) Now assume that your team decides to use yielding as the failure criteria and an additional constraint is added to the system: the ductility of the rod cannot be less than 30% elongation. Using the principles of cold work and Figure 8.19 in the textbook, determine if any of the materials in the table can be used to meet both the loading and ductility requirement. Assume that the starting rod cross section is as stated in 83.2 and note that the stress on the rod will change with decreasing cross section. State the material and show that it satisfies the requirements (if no material meets the requirement, state "none" and still show your work)
