Question 2527 Deck Safety
70% to passYou 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?
A
15.9 seconds
B
17.0 seconds
C
17.6 seconds
D
15.2 seconds
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.
