5.14 Strains are measured on the surface of a brass alloy part as follows: Ex 160010-6 y=1300106, and Yxy = 1500106. Estimate the in-plane stresses x, y, and Txy, and also the strain normal to the surface. (Assume that the gages were bonded to the metal when there was no load on the part, that there has been no yielding, and that no loading is applied directly to the surface, so that z = = Tyz = Tzx =0.)
