Question 2194Deck Safety70% to pass
A vessel is inclined at an angle of loll. In the absence of external forces, the righting arm (GZ) is _______________.
AI Explanation
The correct answer is B) zero.
In the absence of external forces, when a vessel is inclined at an angle of loll, the righting arm (GZ) is zero. This is because at the angle of loll, the vessel's center of gravity (G) is directly above the center of buoyancy (B), and there is no righting moment or righting arm to restore the vessel to the upright position.
The other options are incorrect because: A) the righting arm is not vertical, as it is zero at the angle of loll; C) the righting arm is not positive, as it is zero; and D) the righting arm is not negative, as it is zero.
