3. An opening in a dam is covered with a plate of 2 m square and is hinged on the top and inclined at 60° to the horizontal. If the top edge of the gate is 1 m below the water level, what is the force required to open the gate by pulling a chain set at 45° angle with the plate and set to the lower end of the plate? The plate weight is 2200 N.
