Inclining Experiment — Lesson 3

This lesson covers the concept of an inclining experiment, a crucial test conducted during the construction of a vessel. The primary goal of this experiment is to calculate the position of the center of gravity of the vessel (KG), but the actual calculation performed during the experiment is GM. The lesson explains the process of the inclining experiment, where a pendulum is hung from a point on the vessel and a small weight is shifted from one side to the other, causing the vessel to incline. The lesson also discusses the importance of stability calculations and the role of hydrostatic data in these calculations. It further explains the concept of Bonjean curves and their role in calculating the displacement of a vessel.
