Challenge Problems
Push your limits with advanced challenges
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.
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.
