🔍 Key Concepts

• KG (height of center of gravity) and how removing a weight affects it • The moment created by a weight: weight × vertical distance • The formula for new KG after weight removal on a ship or MODU

💭 Think About

• First compute the total moment of the MODU before discharging the weight using its displacement and KG. What is that value? • Compute the moment of the removed weight using its weight and VCG. Then, what happens to the total moment when you remove this weight? • After removal, you have a new displacement and a new total moment. How do you find the new KG, and then the change in KG?

✅ Before You Answer

• Be sure you change the displacement after the weight is discharged (subtract the discharged weight). • Use consistent units (all long tons and feet) when calculating moments. • After finding the new KG, carefully compute old KG − new KG to get the magnitude of the downward change and compare with the answer choices.
