A circular plate, 50 cm in diameter, is placed vertically in oil of specific gravity 0.9. The center of the plate is located 2 m below the oil surface. Calculate the coca! Force acting on one side and its point of action.

A 10.0-m-long vertical wall separates seawater (specific gravity, S.G. = 1.025) from freshwater. If the depth of seawater is 8 m, what depth of freshwater is required to give zero resultant force? Calculate the moments at the toe of the wall.
