13. A column is to be supported by a 2.0 m wide square footing that is buried 1.0 m from the ground surface. The soil beneath the footing is sand with an effective cohesion of 0, an effective friction angle of 32 degrees, and a unit weight of 18.5 kN/m. The groundwater table is 20 meters below the ground surface. Compute the maximum allowable column load if the factor of safety against a bearing failure must be 2.5.
