In the DEEP DRILLER, VCG is obtained from the sum of the vertical moments by _______________.
AI Explanation
The correct answer is B) dividing by displacement.
The vertical center of gravity (VCG) is obtained by taking the sum of the vertical moments and dividing it by the total displacement of the vessel. This is because the VCG represents the vertical position of the center of gravity, which is calculated by balancing the moments about a reference point, usually the keel. Dividing the sum of the vertical moments by the displacement gives the vertical distance of the center of gravity from the reference point.
The other options are incorrect because multiplying by displacement would not give the VCG, subtracting displacement does not make sense in this context, and adding displacement would not properly calculate the vertical position of the center of gravity.
