SITUATION. Consider the figure shown below, neglect the self-weight of members AB and BC. 2.0 m E 0.9 m+0.9 m 0.8 m 0.4 m W 5.4 kN O Zoom image

Refer to Figure P6.4. A strip load of q = 900 lb/ft2 is applied over a width B = 36 ft. Determine the increase in vertical stress at point A located z = 15 ft below the surface. Given: x = 27 ft. Figure P6.4

Two line loads q1 and q2 of infinite lengths are acting on top of an elastic medium, as shown in Figure P8.6. Find the vertical stress increase at A.

Solve Problem 15 .17 for the loading shown in Fig. P15.17 and a settlement of 50 mm at support D. FIG. P15.17, P15.21
