4. Draw a free body diagram of the loading and forces. Solve for the reaction A at the wall support. Check your answer using the summation of forces. 10k A w=2 k/ft 40ft 10ft 5k

Consider the structure shown in (Figure 1). Suppose that F = 2500 N. Figure 0.2 m 1500 N 0.2 m 30% 0.2 m B -0.2 m-0.2 m- F Part A Determine the resultant couple moment. Express your answer to three significant figures and include the appropriate units. Enter positive value if the moment is counterclockwise and negative value if the moment is clockwise.

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.
