The Altus dam in Problem 2.97 is made of concrete with a density of \(150 \mathrm{lbm} / \mathrm{ft}^{3}\). The coefficient of friction \(\mu\) between the base of the dam and the foundation is 0.65. Is the dam likely to slide downstream? Consider a unit length of the dam \((b=1 \mathrm{ft})\).

Problem 2.97

Figure P2.97 is a representation of the Altus gravity dam in Oklahoma. Find the magnitudes and locations of the horizontal and vertical hydrostatic force components acting on the headwater wall of the dam and on the tailwater 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 \((b=1 \mathrm{ft})\).
