In Problem 6.70, if the specimen has a cross-sectional area of 0.25 in.2 and a gauge length of 2, plot the engineering stress-strain diagram for the unknown metal. Estimate (a) the 0.2% offset yield strength, (b) the modulus of elasticity, (c) ultimate tensile strength, (d) percent elongation at failure, (e) modulus of resilience, and (f) toughness. What is the difference between the results here and those in the previous problem (you must solve the previous problem). Which of these properties can help you identify the general metal alloy category?
