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.

Solve the following problem of a steel tensile plate with a concentrated load applied at the top, as shown in Figure P7–14. Determine at what depth the effect of the load dies out. Plot stress σ_y versus distance from the load. At distances of 1 in., 2 in., 4 in., 6 in., 10 in., 15 in., 20 in., and 30 in. from the load, list σ_y versus these distances. Let the

width of the plate be b = 4 in., thickness of the plate be t = 0.25 in., and length be L = 40 in. Look up the concept of St. Venant’s principle to see how it explains the stress behavior in this problem.
