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)
