Which of the following formulas is an acceptable method to calculate the vertical shift of the vessel's center of gravity?

🔍 Key Concepts

• Shift of center of gravity formula from basic statics of moments: ‘moment = force × distance’ • Relationship between weight shifted (W), displacement (Δ), and shift of G (GG') • Use of dimensional (unit) analysis: what units should GG' have?

💭 Think About

• Start from the idea that when a weight is moved, the total moment about a reference point must balance before and after the shift. How is that written in equation form? • Ask yourself: GG' is a distance. Which expressions in the options will produce a distance when you look at the units? • Identify which term in the problem represents the vessel’s total displacement, and which represents just the weight moved. How should those appear in the numerator or denominator if GG' gets larger when you move a larger weight farther?

✅ Before You Answer

• Confirm that GG' ends up alone on the left side of the formula and has units of length (feet or meters). • Verify that the numerator represents a moment (weight × distance), not just a weight or just a distance. • Check that the denominator is the vessel’s displacement, not the weight being shifted and not GG' itself.

Question 1 of 27070

Which of the following formulas is an acceptable method to calculate the vertical shift of the vessel's center of gravity?

GG' = Displacement/ (WxD)

Displacement = W/ (DxGG')

GG'= (WxD)/Displacement

GG'= (Displacement)x (DxW)
