The concrete (specific weight \(=150 \mathrm{lb} / \mathrm{ft}^{3}\) ) 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 \(A\) ).
