Question 1996 Deck Safety
70% to passThe upward pressure of displaced water is called _______________.
A
freeboard
B
deadweight
C
draft
D
buoyancy
AI Explanation
The correct answer is D) buoyancy. The upward pressure of displaced water is the buoyant force that acts on an object submerged in a fluid. This buoyant force is equal to the weight of the fluid displaced by the object, as described by Archimedes' principle. This upward buoyant force counteracts the downward force of gravity, allowing objects to float. The other options are incorrect because: A) Freeboard is the distance between the waterline and the top of the deck. B) Deadweight is the total weight an object can safely carry or support. C) Draft is the depth of a vessel's keel below the waterline.
