2 cards from this section. Quick, good the night before a test.
What is the diameter of the elliptical gate in the example?
Look for dimensional values in the setup.
What is the depth of water above the gate?
Recall the water level mentioned in the problem statement.
What pressure is calculated at the centroid of the elliptical gate?
Use the density and depth values given.
Is the resultant force required to open the gate dependent on water depth?
Recall how pressure changes with depth.
Calculate the total force required to open an elliptical gate with a depth of 15 meters of water above it if the dimensions remain the same as in the example.
Make sure to account for the height change in pressure.
If the weight of the gate was taken into account and was 2000 N, how would that affect the force required to open the gate?
Remember, net force is the resultant minus any counter forces.
