For the axisymmetric elements shown in Figure P9-4, determine the element stresses. Let E = 15 × 106 psi and v = 0.25. The coordinates (in inches) are shown in the figures, and the nodal displacements for each element are u1 = 0.0001 in., w1 = 0.0002 in., u2 = 0.0005 in., w2 = 0.0003 in., u3 = 0, and w3 = 0?
