Question 1 of 27070

Q

At an angle of loll, the capsizing moment is __________.

🔍 Key Concepts

• Angle of loll occurs in a vessel with negative GM (metacentric height) when upright • Relationship between GZ (righting arm) and capsizing moment • What happens to the righting/capsizing moment when the vessel is in an equilibrium heel position

💭 Think About

• Think about what it means for the ship to be in a new "resting" heeled position—are the moments balanced or unbalanced at that angle? • If the ship is not rolling further and has settled at a steady heel, what must be true about the net heeling/capsizing moment at that instant? • How does the righting arm (GZ) behave exactly at the angle of loll—does it have a value, reach an extreme, or pass through a particular condition?

✅ Before You Answer

• Recall that at an angle of loll, the vessel has moved from the upright position to a new equilibrium position • At an equilibrium position, total moments about the center of buoyancy/center of gravity must be checked—are they causing further heel or are they balanced? • Verify whether the righting arm (GZ) at the angle of loll is: negative, positive, maximum, or crossing through zero
