Question: A cylindrical rod 380 mm (15.0 in.) long, having a diameter of 10.0 mm (0.40 in.), is to be subjected to a tensile load. If

A cylindrical rod 380 mm (15.0 in.) long, having a diameter of 10.0 mm (0.40 in.), is to be subjected to a tensile load. If the rod is to experience neither plastic deformation nor an elongation of more than 0.9 mm (0.035 in.) when the applied load is 24,500 N (5500lbf), which of the four metals or alloys listed below are possible candidates? Justify your choice(s).

Modulus of Elasticity Yield Strength Tensile Strength (MPa) 420 Material (GPa) 70

Modulus of Elasticity Yield Strength Tensile Strength (MPa) 420 Material (GPa) 70 (MPa) 255 Aluminum alloy 345 Brass alloy 100 420 290 Copper Steel alloy 110 250 207 450 550
