Which factor has the greatest effect on the value of the free surface correction?

Question 1 of 27070

Which factor has the greatest effect on the value of the free surface correction?

🔍 Key Concepts

• Free surface effect and how it reduces a vessel's stability (metacentric height, GM) • How moment of inertia of the liquid surface changes with tank dimensions • Relationship between tank breadth (width) and the heeling moment caused by liquid shift

💭 Think About

• Think about which tank dimension makes the liquid’s center of gravity move the farthest when the ship heels slightly. • Ask yourself: if you doubled each listed factor one at a time, which change would most strongly increase the heeling moment from the free surface? • Consider which option directly affects the transverse (side‑to‑side) movement of the liquid, rather than just its volume or weight.

✅ Before You Answer

• Verify which geometric property of the tank appears in the free surface moment (FSM) or free surface correction (FSC) formula in stability references. • Check which factor primarily affects the transverse second moment of area of the liquid surface. • Confirm that you are focusing on the shape and orientation of the tank relative to the ship’s centerline, not just how full or heavy the tank is.
