A vertical dam on a large lake is 30 ft tall and 60 ft wide, and the water level is 5 ft below the top of the dam. In the middle of the dam at the very bottom is a gate in the shape of an equilateral triangle 10 ft on a side as shown in the figure below. (Assume a density of water p = 62.4 lb/ft.) 10 ft 25 ft Find the hydrostatic force (in lb) on the gate. (Round your answer to the nearest integer.) lb
