A 4-foot square footing has its bottom 2.03 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 114 lb/ft3, Saturated unit weight is 122 lb/ft3, cohesion = 97 lb/ft2. Use angle of internal friction = 30° (Nc = 35.4, Nq = 29.1, = 19.7). Compute the allowable load (in lb) that the footing could carry. Use FS = 2.9. Round off to the nearest whole number.
