🔍 Key Concepts

• Longitudinal center of gravity (LCG) and how adding/removing weight changes it • Using moments about amidships: weight × distance • Effect of discharging weight forward of amidships on LCG position

💭 Think About

• Write the total initial longitudinal moment of the MODU using its displacement and initial LCG. • Subtract the moment and weight of the discharged cargo to find the new total moment and new displacement. • Divide the new total moment by the new displacement to find the new LCG, then compare it to the answer choices.

✅ Before You Answer

• Be consistent with sign convention (treat "forward of amidships" all the same way). • Use the correct new displacement after discharging weight (original minus discharged). • Keep track of units (short tons and feet) and make sure you are dividing moment (ton-feet) by displacement (tons).
