For the linear-strain elements shown in Figure P8–5, determine the strains ε_x; _y, and γ_xy. Evaluate the stresses σ_x; σ_y, and τ_xy at the centroids. The coordinates of the nodes are shown in units of inches. Let E = 30 × 10⁶ psi, n = 0.25, and t = 0.25 in. for both elements. Assume plane stress conditions apply. The nodal displacements are given as

(Hint: Use the results of Section 8.2.)
