3 cards from this section. Quick, good the night before a test.
What is the formula for pressure at a certain depth in a fluid?
Think about how pressure increases with depth.
Define buoyant force in your own words.
Consider what happens when you put something in water.
What does the resultant force FR on a submerged surface depend on?
Think about how both pressure and area affect the force.
Is the center of pressure always at the centroid of the submerged area?
Consider how pressure variations affect this.
You have a submerged rectangular surface with area A at a depth of h in water. Calculate the resultant force and location of the center of pressure if the second moment of inertia is known.
Make sure to understand how to derive each component.
For a triangular surface submerged in water, with the top at depth h and a base width b, derive the equation for the center of pressure including the necessary integration steps.
Consider how the triangle’s height affects the center of pressure calculation.
