![]() ![]() ![]() In each case, an opposing force is created by filling the tank with water. The gates are connected to a known weight by a string (W1, W2 or W3), which applies a point force to the gate (and therefore a moment about the hinge) in such an arrangement that it either holds the gate shut or pulls it open. In this experiment, you will see several tanks, each with a hinged gate on the side. Watch this short video of the locks operating on the Panama Canal. The pressure on a submerged surface (in this case a gate) creates a distributed load, which can be considered to be an equivalent point load (single force) acting through the centre of pressure.īy converting the distributed load to an equivalent single force, and knowing the location where that force acts on the surface, you can determine the moment generated by the water pressure. In this experiment, you will combine your mechanics knowledge, with what you know about hydrostatic forces, to determine the moment generated by water pressure in three different tanks (bays) with rectangular, circular and triangular gates. Lock gates, such as this one from Blanchetown, South Australia, are an example of where it may be necessary to calculate such hydrostatic forces.īut how do you calculate such pressure measurements?
