Study Notes
Metacentric Height
- Metacentric height is a measure of a vessel's initial stability, representing the distance between the center of gravity and the metacenter.
- A larger metacentric height implies a higher stability and resistance to capsizing.
- In passenger ships, an ideal metacentric height is considered around 1-2 meters to provide a comfortable and stable ride.
Natural Period of Rolling
- The metacentric height affects the natural period of rolling, with a higher metacentric height resulting in a shorter period of rolling.
Fig. 1 Apparatus
- The apparatus shown in Fig. 1 consists of an inclining experiment setup, used to measure the metacentric height of a vessel.
