Spring 2023 Q3. A cylindrical specimen of aluminum having a diameter of 12.5 mm and a gauge length of 50.80 mm is pulled in tension. Use the load-elongation characteristics tabulated below to complete parts (a) through (f). *Hand-drawing plot won't be graded.

(b) Compute the modulus of elasticity. (c) Determine the yield strength at a strain offset of 0.002 with using a plot you made in (a). (d) Determine the tensile strength of this alloy. (e) What is the approximate ductility (*total amount of plastic strain), in percent elongation? (f) Generate a true stress-true strain plot for aluminum. The equation relating engineering and true values becomes invalid past the point at which necking begins; therefore, measured diameters are given below for the last four data points, which should be used in true stress computations.
