🔍 Key Concepts

• Transverse Center of Gravity (TCG) and how adding weight off the centerline shifts it • The basic shift-of-G formula: GG' = (w × d) ÷ W (added weight × distance from centerline ÷ displacement) • Sign convention: which direction is considered positive when weight is added to starboard

💭 Think About

• If the unit was exactly upright (TCG at centerline) before loading, where will the new TCG lie after adding a weight to starboard? • How big is the ratio w ÷ W in this problem, and what does that tell you about whether the shift should be very small or fairly large? • After you compute GG', compare your numerical result with the choices: which one is closest to your calculated shift in feet to starboard?

✅ Before You Answer

• Use W = 18,000 long tons as the total displacement and w = 400 long tons as the added weight • Use d = 80 ft as the transverse distance from centerline to the P-tanks • Make sure your calculator steps follow GG' = (w × d) ÷ W exactly, and that you express the final answer as a distance in feet to starboard of centerline
