Question 2484Deck Safety70% to pass
On a vessel of 15,000 tons displacement, compute the reduction in metacentric height due to free surface in a hold having free water in the tank tops. The hold is 50 feet long and 60 feet wide. What is the reduction in metacentric height?
AI Explanation
The correct answer is D) 1.71 feet.
To calculate the reduction in metacentric height due to free surface in a hold with free water, we can use the formula:
Reduction in GM = bl^2 / 12 * Displacement
Where:
b = width of the hold (60 feet)
l = length of the hold (50 feet)
Displacement = 15,000 tons
Plugging in the values, we get:
Reduction in GM = 60 ft * 50^2 ft^2 / 12 * 15,000 tons
= 1.71 feet
The other answer choices are incorrect because they do not match the result calculated using the formula for free surface effect.
