What does metacentric height indicate?
Think about what keeps a ship upright.
Is a high rolling period preferable for ship stability?
Consider how quickly a ship returns to an upright position.
If a ship has a metacentric height of 0.5 m and a rolling period of 18 seconds, determine the relevant radius of gyration.
Follow the formula steps carefully to derive radius.
