2) The following engineering stress-strain data were obtained at the beginning of the tensile test for a metal. (Note that these data only give the beginning part of the stress-strain curve) i. Plot the engineering stress-strain curve for these data. ii. Determine the 0.2 percent offset yield stress for this steel. iii. Determine the modulus of elasticity of this steel Engineering Stress Engineering Strain (MPa) (mm/mm) 15 0 15 0.0005 30 0.0010 40 0.0015 50 0.0020 60 0.0035 66 0.0040 70 0.0060 72 0.0080
