For the cantilever retaining wall shown below. Calculate the factor of safety with respect to overturning, sliding, and bearing capacity. Wall dimensions: H=5.49 m, D=1.22 m, α=0°, X₁=0.46m, x2=0.58m, x3=0.92m, X4=1.55m, x5-0.61m. Soil properties: Y₁ 18.08 kN/m³, 1'=36°, Y2=19.65 kN/m³, 2²=15°, C₂ = 44 kN/m² X₁ H 72 $2
A 1.4 m wide x 0.39 m thick RC footing is to be provided for a 0.22m thick RC wall. Use f'c = 22 MPa and fy = 420 MPa. Unit weight is 24.9 kN/m3 for concrete and 17.95 kN/m3 for the soil backfill. The gross allowable soil pressure is 222 kPa. The wall transfers a dead load = 195 kN/m and a live load = 156 kN/m to the footing. Use 12mm diameter bars. Consider a footing depth of 863mm. What is the value of capacity minus demand in one-way shear? Answer in kN. If the value is negative, include the negative sign. Please answer it asap. For upvote. Thanks

Describe the role of each of the structural features circled in red of theretaining wall (arm or stem, heel, key and toe) depicted in Figure Q2(b)aimed at resisting the pressures/stresses being imposed on the retainingwall by the mass of soil, mass of the retaining wall and any moisturecontained in the soil. Make particular references to the actions of normalstresses, shear stresses and bending moments.
In retaining walls, what happen when lateral soil pressure exceeds the weight of the wall (its slab + its heel)? Hint: the wall cross section is ideal with toe and shear key. wall overtunes wall slides wall develops excessive bearing oressure
