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?
