A cylindrical rod 600 mm long and having a diameter 13.2 mm is to be subjected to a tensile load. If the rod is to experience neither plastic deformation nor an elongation of more than 1.4 mm when the applied load is 30 KN. Which of the four metals or alloys listed below are possible candidates. Justify the answer with calculations Material modulus of elasticity(gpa) yield strength(mpa) tensile strength(mpa) Aluminium alloy 70 255 420 Brass alloy 100 345 420 Copper 110 210 275 Steel alloy 207 450 550
