A strip footing of width 3 m is founded at a depth of 2 m below the ground surface in a soil having a cohesion c = 30 kPa and angle of shearing resistance = 35. The water table is at a depth of 5 m below ground level. The moist weight of soil above the water table is 17.25 kN/m3. (For =35*, Nc = 57.8, Nq=41.4, and Ny-42.4).
