please be very 100% sure before doing. thank you (1) (25 points) Load-elongation dataset were obtained from a tensile test of high-strength steel as shown in the table. The test specimen had a diameter of 0.505 in. and a gage length of 2.00 in. The Poisson's ratio of high-strength steel is found to be 0.33 At fracture, the elongation between the gage marks was 0.12 in and the minimum diameter was 0.42 in 1) Plot the engineering stress-strain curve using...
