A round bar is 400 mm long and has a diameter 50 mm. The material of the bar has the stress-strain curve shown. Assuming that the bar is subjected to a tensile force P=20 kN the elongation of the bar will be most closely equal to: Stress (MPa) 50 40 30 20 10 0.000 0.005 0.010 0.015 0.020 0.025 0.030 0.035 0.040 Strain 1.5 mm 3 mm 2 mm 2.5 mm
