Question

Explian step by step please

A load of 140,000 N (31,500 lbf) is applied to a cylindrical specimen of a steel alloy (displaying the stress-strain behavior shown in Figure below) that has a cross-sectional diameter of 10 mm (0.40 in.) (a) Will the specimen experience elastic and/or plastic deformation? Why? (b) If the original specimen length is 500 mm (20 in.), how much will it increase in length when this load is applied? 300 2000 103 psi MPa 300厂2000 200 200 1000 1000 100 100 0 0000 0.005 0.010 0.015 Strain 0 0.000 0.020 0.060 0.040 0.080
