Question

Solve only 15.11

15.10 A square footing (B X B) must carry a gross allowable load of 670 kN. The base of the footing is to be located at a depth of 0.92 m below the ground surface. For the soil, we are given that y = 18.1 kN/m³, c' = 0, and o' = 40°. If the required factor of safety is 3, determine the size of the footing. Use Terzaghi's bearing capacity factors and general shear failure of soil.
