A 2-foot square footing has its bottom 2.98 ft. below the ground surface. The ground water table is located at a depth of 4 ft. below the ground surface. Unit weight of soil is 117 lb/ft3, Saturated unit weight is 122 lb/ft3, cohesion = 95 lb/ft2. Use angle of internal friction = 30° (Nc = 35.2, Nq = 29, = 19.8). Compute the allowable load (in lb) that the footing could carry. Use FS = 2.3. Round off to the nearest whole number.
