Question

a) What is the approximate Yield Strength of this material? Identify this point on the curveabove and label it. (2pts) b) What is the approximate Tensile Strength of this material? Identify this point on the curve above and label it. (2pts) c) Is this stress-strain curve indicative of a ductile or brittle material? (1pt) d) If a sample was initially 100 mm long what is the change in length (A/) of this material after fracture has occurred? (2pts) e) A cylindrical specimen of this alloy 12 mm in diameter and 91 mm long is pulled intension; after the load is released the final length is 99 mm. Calculate the magnitude of the load (in N) necessary to cause this elongation. (3 pts)
