Question 1
What does the radius of gyration measure?
- Mass distribution
- Weight
- Volume
- Density
💡 Hint: Think about why this would be important for stability.
Question 2
True or False: A larger radius of gyration means a ship is more stable.
- True
- False
💡 Hint: Think of the ship's ability to respond to waves.

Challenge Problems
Push your limits with challenges.
Question 1
A ship has an inertia of 2000 kg·m² and a mass of 500 kg. Calculate its radius of gyration, then discuss how this would influence its rolling period in waves.
💡 Hint: Think about how increasing mass affects the ship's behavior.
Question 2
If a ship's metacentric height is 0.8m and radius of gyration is 2m, how does this reflect its stability under maximum loading conditions?
💡 Hint: Consider how weight distribution might affect height.
