A structure has 39 ft of soil on the left side with the water table at the ground surface. On the right side there is 13 ft of water above soil. The height of the structure is the same on the left and the right. The unit weight of soils is 119 pcf. Neglecting resistance along the bottom of the structure, what is the factor of safety against sliding assuming full passive resistance? Assume that movement of the structure is from left to right. The soil friction angel is 30 degrees.
