Question:

Figure 13.10 shows a frictionless wall with a sloping granular backfill. Given: H = 4 m, Î± = 10°, Ï•' = 33°, and Î³ = 19 kN/m3.
a. Determine the magnitude of active pressure, Ïƒ'a, at the bottom of the wall. Also, state the direction of application of Ïƒ'a
b. Determine the Rankine active force, Pa, per unit length of the wall and its location and direction.
