🔍 Key Concepts

• Metacentric height (GM) definition in small-angle stability • Relationship between KM, KG, and GM • How righting moment is calculated for small angles of heel

💭 Think About

• Which option correctly describes how GM is obtained from vertical center of gravity (KG) and height of metacenter above keel (KM)? • Think about whether GM itself is always positive, or if it can be negative depending on the ship’s loading and KG. • Recall the formula used to find the righting moment at small angles—what quantities are multiplied together in that formula?

✅ Before You Answer

• Verify the standard formula: GM = KM − KG and see which choice matches that wording. • Check whether GM is something you read directly from hydrostatic tables, or something you must compute from other values. • For righting moment, confirm whether the formula includes GM × displacement × sin(heel angle), and see if any option is missing a required factor.
