Using the provided tensile test measurements of force and displacement for steel, brass and
aluminum, calculate and plot the stress vs. strain curve, fine the yield strength, Young’s modulus,
ultimate tensile strength, fracture stress, and calculate the modulus of toughness. The center section
of each sample has an approximate diameter of 3.3 mm, and initial length of 40 mm.
