Q6: The following stress-strain curve is for a copper alloy (Figure 1 and Figure 2). At fracture, the total length was 53 mm, and the diameter was 10 mm. The initial length and diameter were 50.8 mm and 12.8 mm respectively. Determine: a) the 0.2% offset yield strength b) the ultimate tensile strength UTS c) the modulus of elasticity E d) engineering stress and strain at fracture e) true stress and true strain at UTS f) true stress and true strain at fracture V
