Question 1 of 29218

🔍 Key Concepts

• Longitudinal moment = weight × longitudinal center (LCG or station) from the reference point • Effect of transferring a liquid: one tank loses its entire moment, the other gains moment based on the same weight at a different LCG • How to use the existing sum of longitudinal moments for liquid variables from Sample Load Form #3 as your starting point

💭 Think About

• From the original load form, what is the current sum of longitudinal moments for the liquid variables before any transfer? • What is the weight in tank #19, what is its longitudinal position, and therefore what moment are you removing? • What is the same weight’s new longitudinal position in tank #13, and what new moment are you adding to get the new total?

✅ Before You Answer

• Carefully read the exact weight and LCG values for tank #19 and tank #13 from Sample Load Form #3 • Confirm that you remove the full moment of tank #19 and add the full moment of tank #13 – don’t just change one side • Re-check that all moments are in ft-kips and that you have not mixed up feet, kips, or inches in your calculations
