A cylindrical specimen of aluminum having a cross-sectional area of 3.50 x 105 m? and a gauge length of 45.5 mm is pulled in tension. The first plot (both plots shown on the next page) shows the entire stress-strain curve, while the second plot is a blown-up version showing the behavior up to just beyond the elastic region of deformation. Using these plots, determine the following values. a. The elastic modulus in GPa b. The 0.2% yield stress c. The tensile stress d. The estimated energy required to break the sample: do not calculate the answer. Merely, indicate how you would obtain the answer. You may use the figure(s) in your explanation.
