Chapter 8, Problem 8.100P

The cylindrical water tank with R = 10 ft and H = 1.6 ft has thin steel walls of uniform thickness and weighs 18000 lb when empty. Determine the depth of the water h for which the center of gravity G of the tank plus water will be located at the surface of the water. For water, use $\gamma =62.4{\text{lb/ft}}^{\text{3}}\text{.}$
