Q8) A cylindrical specimen of a brass alloy 7.8 mm in diameter and 95.0 mm long is pulled in tension with a force of 6000 N; the force is subsequently released. (a) Compute the final length of the specimen at this time. The tensile stressstrain behavior for this alloy is shown in the figure below. (b) Compute the final specimen length when the load is increased to 16,500 N and then released.
