PS: Answer only four questions! 1. (a) Define stress and strain obtained from tension test. Using the stress (0)- strain (8) curve for a metal given in Figure 1 below, determine the following: (i) Yield strength, tensile strength and fracture elongation. Modulus of elasticity. (b) In normal motion, the load exerted on the hip joint in human body is 2.5 times body weight. Calculate the corresponding stress in MPa on an hip joint with a cross-sectional area of 5.7 cm’...
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...
