Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the buoyant force?
- The weight of the object
- The upward force exerted by the fluid
- The force of gravity
💡 Hint: Consider what keeps an object afloat in water.
Question 2
True or False: If the metacenter is below the center of gravity, the floating body is in stable equilibrium.
- True
- False
💡 Hint: Think about object stability when tilted.

Challenge Problems
Push your limits with challenges.
Question 1
Calculate the metacentric height of a boat that has a center of buoyancy that moves up by 0.2 meters when tilted and has a center of gravity at 1 meter above sea level.
💡 Hint: Remember: BM > BG for stability.
Question 2
A floating object tips slightly, moving its center of gravity upward, potentially affecting stability. How would you experimentally determine if the object is stable or unstable?
💡 Hint: Observe and test the recovery behavior after the tilting.
