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 6.22) 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?

Question
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 6.22) 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?
