During a tensile test in which the starting gage length = 125.0 mm and the cross-sectional area = 62.5 mm2 , the following force and gage length data
During a tensile test in which the starting gage length = 125.0 mm and the cross-sectional area = 62.5 mm2 , the following force and gage length data are collected (1) 17,793 N at 125.23 mm, (2) 23,042 N at 131.25 mm, (3) 27,579 N at 140.05 mm, (4) 28, 913 N at 147.01 mm, (5) 27,578 N at 153.00 mm, and (6) 20,462 N at 160.10 mm. The maximum load is 28,913 N and the final data point occurred immediately prior to failure. (a) Plot the engineering stress strain curve. Determine (b) yield strength, (c) modulus of elasticity, and (d) tensile strength.
