Solve the following problems using a computer program. In some of these problems, we suggest that students be assigned separate parts (or models) to facilitate parametric studies.

Determine the free-end displacements and the element stresses for the plate discretized into four triangular elements and subjected to the tensile forces shown in Figure P7–12. Compare your results to the solution given in Section 6.5. Why are these results different? Let E = 30 × 10⁶ psi, n = 0.30, and t = 1 in.
