L1=4.5m soil density=17kN/m

Q2. For the retaining wall and the profile below calculate; (Yc =25 kN/m) a) The base pressures (maximum and minimum) under the retaining wall base. (Sp) b) The safety factor for overturning and for sliding. (7) c) Show all the critical sections, draw FBD for each critical sections and also calculate the shear force and bending moment at the critical sections.
