Prob: 2 a cylindrical specimen of aluminum having a diameter of 0.505 in. (12.8 mm) and a gauge length of 2.000 in. (50.800 mm) is pulled in tension. use the load–elongation characteristics tabulated below and (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) populate that data with corresponding true stress and strain values (g) compute the strain hardening exponent by using the equation
