Question 1 (8 points) A cylindrical specimen of aluminum having a diameter of 0.543in.(13.8mm) and a gauge length of 2.07in.(52.6mm) is pulled in tension. Use the following engineering stress-strain curve to answer the following: (a) Compute the modulus of elasticity. (b) Determine the yield strength at a strain offset of 0.002 . (c) What is the approximate ductility, in percent elongation? (d) Compute the modulus of resilience. (e) If the specimen is pulled in tension with a force of 46,200N, calculate the reduction in specimen diameter if it is known that this specimen has a Poisson's ratio of 0.30 .
