Deck General · Metacentric Height (GM)
In the inclining experiment formula GM = (w x d) / (W x tan θ), what does 'W' represent?
- AThe weight of the inclining mass moved
- BThe vessel's displacement at the time of the experiment✓ Correct
- CThe width of the vessel at the waterline
- DThe moment to trim one inch
Explanation
W is the total displacement (weight) of the vessel during the experiment. The heeling moment (w x d) is divided by (W x tan θ) to give GM. Accurate displacement requires careful draft readings and density measurement during the experiment.
