The Keswick dam in Problem  2.94 is made of concrete and has a specific weight of \(150 \mathrm{lb} / \mathrm{ft}^{3}\). The hydrostatic forces and the weight of the dam produce a total vertical force of the dam on the foundation. Find the magnitude and location of this total vertical force. Consider a unit length of the dam \((b=1 \mathrm{ft})\).

Problem  2.94

Figure P2.94 is a representation of the Keswick gravity dam in California. Find the magnitudes and locations of the hydrostatic forces acting on the headwater vertical wall of the dam and on the tailwater inclined wall of the dam. Note that the slope given is the ratio of the run to the rise. Consider a unit length of the dam ( \(b=1 \mathrm{ft}\) ).
