(a) Draw two Engineering Stress - Engineering Strain graphs: one for a ductile metal and one for a brittle metal, marking and labelling on both graphs the Yield Stress, the Ultimate Tensile Stress, the Fracture Stress, the region in which necking occurs. Correctly label all graph axes and give correct units. (b) A cylindrical rod made from an unknown metal is 350mm long and has a diameter of 10mm. The rod is subjected to a tensile load. It experiences only elastic deformation and elongates by less than 1.0mm under an applied load of 19,800N. Could any of the four metals listed in the table below could be the unknown metal? If so which ones and why? Material Modulus of Elasticity / GPa Yield Strength / MPa Ultimate Tensile Strength / MPa 420 70 255 Aluminium alloy Brass Copper alloy Steel 100 110 207 345 250 450 420 290 550
