Q

Longitudinal moment is obtained by multiplying a vessel's weight and which other component?

🔍 Key Concepts

• Meaning of longitudinal moment in stability/trim calculations • Difference between LCG/LCB (longitudinal centers) and TCG/VCG (transverse/vertical centers) • How a moment is generally calculated (force or weight × distance)

💭 Think About

• Ask yourself: In which direction does a longitudinal moment act, and what type of distance must be involved? • Which of the options represents a distance measured fore-and-aft along the length of the vessel, rather than up/down or side-to-side? • Recall: When calculating a trimming moment about midships or another reference, which "center" value do we multiply by the weight?

✅ Before You Answer

• Identify which choices are centers of gravity or buoyancy in the longitudinal direction only • Eliminate any options that are distances vertically or transversely, since those relate to heel or stability, not trim • Confirm that the remaining option is a linear distance along the ship’s length used in trim/longitudinal moment calculations
