Consider a cylindrical specimen of a steel alloy 8.0 mm (0.3150 in.) in diameter and 89 mm (3.504 in.) long that is pulled in tension. Determine its elongation when a load of 57810 n (13000 lbf) is applied. The tensile stress-strain behavior for this steel alloy is shown in the animated figure 6.22. The answer should be in mm.
