Problem 2. A cylindrical specimen of aluminum having a diameter of $0.505\mathrm{in}.(12.8\mathrm{mm})$ and a gauge length of $2.000\mathrm{in}$. $(50.800\mathrm{mm})$ is pulled in tension. Use the load-elongation characteristics shown in the following table to complete parts (a) through (f). (a) Plot the data as engineering stress versus engineering strain. (b) Compute the modulus of elasticity. (c) Determine the yield strength at a strain offset of 0.002 . (d) Determine the tensile strength of this alloy. (e) What is the approximate ductility, in percent elongation? (f) Compute the modulus of resilience.
