A steel alloy specimen having a rectangular cross section of dimensions 19 mm × 3.2 mm (3/4 in. × 1/8 in.) has the stress–strain behavior shown in Figure 6.22. This specimen is subjected to a tensile force of 110,000 N (25,000 lbf).

(a) Determine the elastic and plastic strain values.

(b) If its original length is 610 mm (24.0 in.), what will be its final length after the load in part (a) is applied and then released?
