A prismatic bar in tension has length L = 2.0 m and cross-sectional area A = 249 mm2. The material of the bar has the stressstrain curve shown in the figure.
Determine the elongation δ of the bar for each of the following axial loads: P = 10 kN, 20 kN, 30 kN, 40 kN, and 45 kN. From these results, plot a diagram of load P versus elongation δ (load-displacement diagram).
