For the axisymmetric elements shown in Figure P9-7, determine the element stresses. Let E = 105 GPa and v = 0.25. The coordinates (in millimeters) are shown in the figures, and the nodal displacements for each element are

u1 = 0.05 mm w1 = 0.03 mm

u2 = 0.01 mm w2 = 0.01 mm

u3 = 0.0 mm w3 = 0.0 mm
