🔍 Key Concepts

• Longitudinal metacenter (KML) and how it is read or calculated from the Sample Load Form #2 • Effect of removing bulk materials on vertical center of gravity (KG) and longitudinal metacentric height (GMl) • Difference between initial (intact) condition and after-discharge condition on the load form

💭 Think About

• Look at the Sample Load Form #2: identify the column or line where the longitudinal metacenter (or KML) is listed for both the original and the ballast-to-survival condition. How does discharging bulk materials change those values? • When you remove bulk cargo, how do the total displacement and total moments change? Think carefully: if weight goes to zero in a tank, what happens to that tank’s moment in the summation and how does that affect the calculated metacentric quantities? • Compare the resulting longitudinal metacenter value you compute to the answer choices—does your value increase or decrease compared to the original, and is that trend physically reasonable for this loading change?

✅ Before You Answer

• Verify you are using the correct line/condition on Sample Load Form #2 labeled for “all bulk materials discharged” or equivalent wording • Double-check the total displacement (Δ) and total longitudinal moment you are using after discharge—they must exclude the removed bulk cargo • Confirm you are reading or calculating the longitudinal metacenter (KML) itself, not confusing it with GMl or another stability parameter in the table
