SHIP STABILITY IN NAVAL ARCHITECTURE

Which term refers to the distance between a ship's center of gravity (G) and its metacenter (M)?

• Metacentric height (GM)

• Righting arm

• Angle of loll

• List

What is ship stability?

• The ability of a ship to float

• The ability of a ship to resist rolling and capsizing

• The speed of a ship in calm waters

• The strength of a ship's hull

What does a positive metacentric height (GM) indicate about a ship's stability?

• The ship is unstable

• The ship is neutrally stable

• The ship is dynamically stable

• The ship is statically stable

What is the angle of loll in ship stability?

• The angle of list due to wind forces

• The angle of heel caused by cargo shifting

• The angle at which a ship remains at rest in equilibrium due to asymmetrical flooding

• The maximum allowable heel angle for a ship

Which factor can lead to an angle of loll in a ship?

• Even distribution of cargo

• Symmetrical loading of fuel

• Flooding of one side of the ship

• Stable metacentric height

How can the angle of loll be corrected?

• By increasing the ship's speed

• By redistributing ballast or cargo

• By reducing the ship's draft

• By increasing the ship's metacentric height

Which term describes the lever arm that restores a heeling ship to its upright position?

• Metacentric height (GM)

• Righting arm

• List

• Freeboard

What safety precaution helps prevent an angle of loll in a ship?

• Monitoring cargo loading

• Increasing engine power

• Decreasing ballast

• Ignoring weather conditions

Why is understanding ship stability crucial for safe maritime operations?

• To increase cargo capacity

• To reduce fuel consumption

• To prevent capsizing and ensure crew safety

• To improve communication systems

What does a negative metacentric height (GM) indicate about a ship's stability?

• The ship is unstable

• The ship is neutrally stable

• The ship is dynamically stable

• The ship is statically stable
