Question 2190Deck Safety70% to pass
For a vessel inclined by the wind, multiplying the buoyant force by the horizontal distance between the lines of action of the buoyant and gravity forces gives the _______________.
AI Explanation
The correct answer is C) righting moment.
When a vessel is inclined by the wind, the buoyant force acts on the vessel's center of buoyancy, while the gravity force acts on the vessel's center of gravity. The horizontal distance between the lines of action of these two forces is called the righting arm. Multiplying the buoyant force by the righting arm gives the righting moment, which is the force that tries to return the vessel to an upright position.
The other options are incorrect because:
A) Longitudinal moment refers to the moment about the vessel's longitudinal axis.
B) Transverse moment refers to the moment about the vessel's transverse axis.
D) Vertical moment does not accurately describe the moment generated by the inclined forces.
