Question 2038 Deck Safety
70% to passThe righting moment can be determined by multiplying the displacement by the _______________.
A
center of gravity (CG)
B
longitudinal center of gravity (LCG)
C
righting arm (GZ)
D
vertical center of gravity (KG)
AI Explanation
The correct answer is C) righting arm (GZ). The righting moment is calculated by multiplying the vessel's displacement by the righting arm (GZ), which is the horizontal distance between the center of gravity (CG) and the center of buoyancy (CB). This righting arm creates a stabilizing moment that acts to restore the vessel's upright position when it is heeled or inclined. The other options (CG, LCG, and KG) are not directly used in the calculation of the righting moment, which is why they are incorrect.
