## Question:

(SI Units) In a tensile test, the starting gage length = 100.0mm and the cross-sectional area = 150 mm2. During testing, thefollowing force and gage length data are collected: (1) 17,790 N at100.2 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) 27,480 N at 130.0 mm, and (6) 20,460 N at135.1 mm. The final data point (6) occurred immediately prior tofailure. Yielding occurred at a load of 19,390 N (0.2% offsetvalue), and the maximum load (4) was 28,960 N. (a) Plot theengineering stress strain curve. Determine (b) yield strength, (c)modulus of elasticity, (d) tensile strength, and (e) percentelongation.
