🔍 Key Concepts

• Use the combined center of gravity (KG) formula: total KG = Σ(weight × KG) ÷ Σ(weight). • Find each piece’s vertical center of gravity above the main deck (pipes, pallets, crates, and given drill pipe). • Keep all weights in the same units (either convert long tons to pounds, or pounds to long tons) before calculating moments.

💭 Think About

• For the round pipes and casings lying on deck in a single tier, where is the geometric center of the circle relative to the deck, given their diameters? • For the pallets stacked two high, should you treat them as one tall block, or as two separate pallets each with its own weight and KG? How does that change your moments? • Once you have all individual weights and KGs, how do you combine them to get one overall KG for all cargo? What does this value represent physically?

✅ Before You Answer

• Be sure you have four separate weight groups (I–IV) and that you include all of them in Σ(weight) and Σ(weight × KG). • Verify each KG: casings’ KG = half their diameter above deck; each pallet’s KG is half its own height above where it sits; each crate’s KG is half its height above deck; drill pipe KG is given as 1.11 ft. • After computing the final KG, check whether the result is between the lowest and highest individual KGs; if it’s outside that range, recheck your math.
