(a) Show, for a tensile test, that

If there is no change in specimen volume during the deformation process (i.e., A0l0 = Adld).
(b) Using the result of part (a), compute the percent cold work experienced by naval brass (for which the stress-strain behavior is shown in Figure 6.12) when a stress of 415 MPa (60,000 psi) is applied?
