🔍 Key Concepts

• Look carefully at the Greek letter used for symbol 1 and think about what that letter commonly represents in ship‑stability formulas. • Recall standard naval‑architecture notation: how do we usually denote a vessel’s total weight (ship + load) versus a change in some quantity like draft or trim? • Compare symbol 1 with what you’d expect for something like the centerline—would that normally be a triangle or some kind of vertical reference line?

💭 Think About

• When you see this symbol in stability problems, what quantity is usually being solved for that has the same symbol in the equation? • Which of the answer choices is a single, overall property of the ship at a given loading condition, rather than a small variation or angle? • If this were meant to show an angle of inclination, what symbol (Greek letter) would you normally expect instead, and does that match symbol 1?

✅ Before You Answer

• Verify which quantity in your stability notes is denoted by capital Greek delta (Δ) all by itself, not as part of ΔT or ΔGM, etc. • Confirm that change of draft is usually shown as a delta plus another symbol (for draft), rather than a lone delta symbol. • Make sure the option you choose represents an overall ship property that fits being symbolized by a single Greek letter in most naval-architecture texts.
