A circular tree log is blocking the flow of a stream creating a dam on one side. The log is about 30 inches in diameter. A very thin layer of water flows slowly on the top of the log to the downstream side where the depth of water is about 15 inches. If the length of the dam is 15 ft and specific weight of wood is 40 lbf per cubic ft,, determine the a) magnitude and direction of vertical components of the net force on the log, b) magnitude and direction of horizontal components of the net force, c) magnitude of the net horizontal and net vertical force on the log.
