2- An isolated square footing 2 m × 2 m is founded at a depth of 1.5 m below the ground surface, in an extended layer of C- soil. Soil angle of internal friction ()=25o, while C = 20 kN/m2. Density b = 16.5 kN/m3. Determine the net and gross allowable bearing capacity of this soil at foundation level, assuming a factor of safety equals 3.
