2.123 The concrete (specific weight 150 lb/ft3 ) seawall of Fig.
P2.123 has a curved surface and restrains seawater at a depth of 24
ft. The trace of the surface is a parabola as illustrated.
Determine the moment of the fluid force (per unit length) with
respect to an axis through the toe (point A).
