1- During a tensile test in which the starting gage length =125.0
mm and the cross-sectional area =62.5 mm2, the following
1
force and gage length data are collected (1) 17,793 N at
125.23 mm, (2) 23,042 N at 131.25 mm, (3) 27,579N at
140.05 mm, (4) 28, 913 N at 147.01 mm, (5) 27,578 N at
153.00 mm, and (6) 20,462 N at 160.10 mm. The maximum
load is 28,913 N and the final data point occurred
immediately before failure. (a) Plot the engineering stress
strain curve. Determine (b) yield strength, (c) modulus of
elasticity, (d) tensile strength, and (e) determine the
strength coefficient and the strain-hardening exponent in
the flow curve equation.
