Question 2527Deck Safety70% to pass
You are on a vessel that has a metacentric height of 1.0 foot and a beam of 40 feet. What can you expect the rolling period of the vessel to be?
AI Explanation
The correct answer is C) 17.6 seconds.
The rolling period of a vessel can be calculated using the formula:
T = 2π √(B/GM)
Where:
T = Rolling period (in seconds)
B = Beam of the vessel (in feet)
GM = Metacentric height (in feet)
Given the information provided:
Metacentric height (GM) = 1.0 foot
Beam (B) = 40 feet
Plugging these values into the formula:
T = 2π √(40/1.0)
T = 2π √40
T = 17.6 seconds
The other answer choices are incorrect because they do not match the calculated rolling period of 17.6 seconds based on the provided vessel characteristics.
