Basic Stability Flashcards
What term is used to describe the point around which a ship’s weight is evenly distributed?
Center of gravity
Free surface effect
Metacentric height
Heeling moment
Center of gravity
What does GM stand for in ship stability?
General Maintenance
Gravity Momentum
Geometric Mean
Metacentric height
Metacentric height
What is the Free Surface Effect?
The influence of the ocean’s surface on a ship’s movement
The tendency for the ship to capsize due to water movement within the ship
The impact of wind on the surface of the ship
The ability of a ship to ride smoothly over waves
The tendency for the ship to capsize due to water movement within the ship
What does a positive metacentric height (GM) indicate about a ship?
The ship is unstable and likely to capsize
The ship is stable and unlikely to capsize
The ship is too heavy and needs to be unloaded
The ship is too light and needs additional ballast
The ship is stable and unlikely to capsize
What role does ballast play in maintaining a ship’s stability?
It increases the ship’s speed
It lowers the center of gravity, increasing stability
It raises the center of gravity, decreasing stability
It reduces the ship’s fuel efficiency
It lowers the center of gravity, increasing stability
What is the principle of buoyancy in relation to ship stability?
It is the force that pushes the ship upwards in the water
It is the force that pulls the ship downwards in the water
It is the force that moves the ship forward in the water
It is the force that moves the ship backward in the water
It is the force that pushes the ship upwards in the water
What happens to a ship’s stability when the center of gravity moves above the metacenter?
The ship becomes more stable
The ship becomes less stable
The ship’s speed increases
The ship’s speed decreases
The ship becomes less stable
The point through which all the buoyancy forces on a vessel are considered to act is called:
Metacenter
Center of buoyancy
Center of gravity
Transverse metacenter
Center of buoyancy
Why is it crucial for a ship to have a low center of gravity?
To increase the speed of the ship
To enhance the stability of the ship
To decrease the weight of the ship
To improve the maneuverability of the ship
To enhance the stability of the ship
Trim, in the context of ship stability, is defined as:
The difference in draft between the bow and the stern
The ornamental addition to the ship’s exterior
The angle at which the ship’s mast is set
The speed at which a ship can travel
The difference in draft between the bow and the stern
