Consider a 8-m-long, 8-m-wide, and 2-m-high aboveground swimming pool that is filled with water to the rim. (a) determine the hydrostatic force on each wall and the distance of the line of action of this force from the ground. (b) if the height of the walls of the pool is doubled and the pool is filled, will the hydrostatic force on each wall double or quadruple? why?
