GZ Righting-Arm Curves
Inside this lesson
- Define GZ as the true righting arm and contrast it with the small-angle approximation GM·sinθ
- Identify a GZ curve's key features: maximum GZ, angle of maximum GZ, angle of vanishing stability, range of stability
- Explain qualitatively how the area under the GZ curve relates to dynamical stability
- Use the simulator to see how KG and free-surface effect reshape the curve
