A cylindrical specimen of a brass alloy 10.0 mm (0.3937 in.) in diameter and 120.4 mm (4.740 in.) long is pulled in tension with a force of 11800 N (2653 lbf); the force is subsequently released. The tensile stress-strain behavior for this alloy is shown in the (a) Compute the final length of the specimen at this time. (b) Compute the final specimen length when the load is increased to 29500 N (6632 lbf) and then released.
