A hinged gate is held in position by a

counter weight W as shown in Fig. P. 3.11. The gate is L m

long along the slope and b m wide. The counter weight, W acts

perpendicular to the gate which is inclined at angle ?.

Determine the height of water for the movement of the gate

outwards. Neglect the weight of the gate.
