In a tensile test, the starting gage length = 100 mm and the cross-sectional area = 150 mm^2. During testing, the following force and gage length data are collected: (1) 17,790 N at 100.2 mm, (2) 23,040N at103.5 mm, (3) 27,370 N at 110.5 mm, (4) 28910 N at 122.0 mm, (5) 27,480 N at 130.0 mm, (6) 20.460 N at 135.1 mm. The final data point (6) occurred immediately prior to failu. Yielding occurred at a load of 19,390 N (0.2% offset value), and the maximum load (4) was 28,960 N. (a) Plot the engineering stress strain curve. Determine the yield strength, modulus of elasticity, tensile strength, and percent elongation. Also determine the strength coefficient and the strain-hardening exponent in the flow curve equation.
