🔍 Key Concepts

• Removal of weight effect on KG (vertical center of gravity) • Use of the KG shift formula: (Weight removed × its KG) ÷ Displacement • Sign convention: whether KG moves upward or downward when high weight is removed

💭 Think About

• Ask yourself: when you remove weight from high up on the vessel, should the ship’s KG move closer to the keel or farther from it? • Write out the full shift-in-KG equation using the given numbers (displacement, amount of weight removed, height of the removed weight) before simplifying. • After computing the numerical change in KG, decide whether it should be labeled as an upward or downward movement based on the physical effect.

✅ Before You Answer

• Be sure to convert all weights to the same unit (long tons) and use the total displacement in the denominator. • Check that you used the KG of the removed weight (120 ft), not the ship’s original KG (52 ft), in the numerator of the shift formula. • Confirm your final sign: does removing a high weight make the vessel more or less stable, and does that match the direction (up or down) stated in your chosen option?
