During a tensile test in which the starting gage length = 100.0 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) 23,040 n at 103.5 mm, (3) 27,370 n at 110.5 mm, (4) 28,910 n at 122.0 mm, (5) 27,400 n at 130.0 mm, and (6) 20,460 n at 135.1 mm. the final data point (6) occurred immediately prior to failure. yielding occurred at a load of 19,390 n (0.2% offset value), and the maximum load (4) was 28,960 n. determine the strength coefficient and the strain-hardening exponent in the flow curve equation.
