A square shallow foundation has to carry a gross allowable total mass of 15,290 kg. The depth of the foundation is 0.7 m. The load is inclined at an angle of 20° to the vertical. The soil beneath and above the foundation is sand with effective friction angle of 30° and unit weight of 18 kN/m*. The ground water table is at a depth of 5 m below the bottom of the foundation. Determine the width of the foundation to achieve a factor of safety of 3.
