3 cards from this section. Quick, good the night before a test.
What is buoyancy?
Think about what happens when you drop an object into water.
Define metacentric height.
Where do the weight and buoyant forces act?
What does buoyancy allow objects to do?
Think about what happens when you push an object underwater.
True or False: The center of gravity is the same as the center of buoyancy.
Consider the shape of different floating objects.
A boat has a center of gravity 1.5 meters below the waterline and its center of buoyancy is 2 meters below the waterline. Calculate the metacentric height.
Remember the formula GM = BG when measuring these distances.
Design a floating structure that can support a heavier weight while remaining stable. Describe modifications.
Consider how changing shape and distribution affects buoyancy.
