Q

When positive stability exists, what does GZ represent?

🔍 Key Concepts

• Stability curves and the meaning of GZ on a righting arm curve • Difference between G (center of gravity), Z (point used for the lever arm), and GM (metacentric height) • Relationship between a lever arm and a moment in ship stability

💭 Think About

• On a stability (righting) curve, what does the horizontal distance between the lines of action of buoyancy and gravity represent? • Which option is a length (a lever/arm) and which option is a force or moment? • How are righting moment and displacement related to the quantity represented by GZ?

✅ Before You Answer

• Identify which choices are lengths and which are forces/moments • Recall that GM is metacentric height; compare that to what GZ stands for on a stability curve • Verify how the formula Righting moment = Displacement × (___) is written in your stability notes
