Q5:A rectangular gate is fitted at the base of a reservoir wall with a pivot in the arrangement shown in Fig.(2). The gate is designed to regulate the level of water in the reservoir by opening when the water level to the right, h, reaches a certain depth. The gate has a width of 1.2m and its centre of gravity is 0.3m from the wall. Determine the weight, W, of the gate, if a water level of h=2.779m will just cause the gate to open. pivot 0.9m Fig.2 water
