Determine whether a 20'-wide wall on the chamfer (diagonal face) at the left end can safely support the water in the reservoir at the elevation shown if the wall can support 3500 pounds per square foot. Determine whether a solid wood cylinder (unit weight = 45 pcf) with outside dimensions of radius 6 feet and height 3 feet will float in the reservoir, and, if so, what height will remain above the surface. (Consider orientation such that the height of the cylinder to be upright in the water.)
