Example: Figure shows-a rectangular sluice gate AB, 3 m wide and 4.5-m-long hinged at- A. It is kept elosed by a weight fixed-to the gate. The total weight of the gate and weight fixed to the gate is 515 kN. The center of gravity of the weight and gate is at G. Find the height of the water h which will first cause the gate to open.

Question
I want the solution in a very simplified way, with an explanation of the similarity of triangles
Example: Figure-shows a-rectangular sluie gate AB, 3 m-wide and-4.5-m long hinged at-
A. It is kept closed by a weight fixed to the gate. The total weight of the gate and weight
fixed to the gate is 515 kN. The center of gravity of the weight and gate is at G. Find the
height of the water h which will first cause the gate to open.
