11.5.3. Stable Equilibrium

Try these first

1. 1.

   Define buoyancy.

   Hint

   Think about how objects float.

2. 2.

   What does Archimedes' principle state?

   Hint

   Consider the relationship between weight and the displaced fluid.

3. 3.

   What is buoyancy?

   • A downward force
   • An upward force
   • A lateral force

   Hint

   Think about how objects react when placed in water.

4. 4.

   If a ship's center of gravity is below the metacenter, what is its condition?

   • True
   • False

   Hint

   Relate this to stable equilibrium.

5. 5.

   A floating object has a center of gravity 0.8 m below the metacenter. If it's disturbed, will it return to its original position? Explain why.

   Hint

   Consider the forces acting at those points.

6. 6.

   Describe how the design of a ship can prevent capsizing under heavy winds using principles of buoyancy and stability.

   Hint

   Think about weight distribution and hull design.
