A cube of cast iron with sides of length a = 75 mm (see figure) is tested in a labaratory under triaxial stress. Strain gages mounted on the faces of the block record the following strains: ϵx = -350 X 10- 6 and ϵy = ϵz = -65 X 10- 6 . Calculate the following quantities: (a) the normal stresses σx σy and σz acting on the x, y, and z faces of the element; (b) the maximum shear stress τmax. in the material; (c) the challge ;\.1' in the volume of the block; and (d) the total strain enclg U stored iIl the block. (Assurne E = 96 GPa and v = 0.25.)
