🔍 Key Concepts

• Center of gravity of a combined load: use total moments divided by total weight • Moments about the deck: moment = weight × vertical distance of its CG above the main deck • Consistent units: convert inches to feet and long tons to pounds before calculating

💭 Think About

• For each cargo group (I–IV), where is the center of gravity located vertically, measured from the main deck? Think about stacks that are "2 high" and blocks with a given total height. • Once you know the CG height of each group, how do you combine them to find a single overall CG height for all cargo together? Which formula relates total moment, total weight, and combined CG? • How do the heavier items (like the dry stores containers and anchors) influence the final CG compared to the lighter items?

✅ Before You Answer

• For every item, convert all dimensions to feet and all weights to pounds (remember 1 long ton = 2240 lb and 9 inches = 0.75 ft). • Make sure the CG of stacked identical items is at the mid-height of the stack above the deck, not at the full stack height. • After computing each group’s moment (weight × CG height), add all moments and all weights, then compute combined CG = total moment ÷ total weight and compare that value to the answer choices.
