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 (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 s 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

Figure P7-14

be L = 40 in. Look up the concept of St. Venant's principle to see how it explains the stress behavior in this problem?
