For the axisymmetric elements shown in Figure P9–4, determine the element stresses. Let E = 30 × 10⁶ psi and n = 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 = 0:0006 in., u₃ = 0, and w₃ = 0.
