Example 3.31. Fig. 3.41. shows a rectangular sluice 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 centre 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. Solution.
