You have been asked to make a material selection for a cylindrical mechanical part. The cylindrical rod is 100 mm long and has a diameter of 10 mm. This part will experience tensile stress during its application. The maximum allowable elongation is 0.3 mm because of the space limitations in the mechanical assembly and it must not have plastic deformation. (a) If the applied tensile load is 30KN during operation, would you recommend any of the materials listed below? are candidates? Justify your choice(s). (20 points)
