Question 3370 Deck General

70% to pass

Given the same water depth and line tension, the length of the ground cable of a 90 pound/foot mooring chain compared to the length of the ground cable of a 19 pound/ft wire rope mooring line will be _______________.

A identical
B shorter
C indeterminable
D longer
AI Explanation

The correct answer is D) longer. The length of the ground cable is inversely proportional to the weight per foot of the mooring line material. Since the 90 pound/foot mooring chain is heavier than the 19 pound/foot wire rope, the ground cable length for the chain will be longer than the ground cable length for the wire rope, given the same water depth and line tension. The other options are incorrect because: A) The ground cable lengths would not be identical, as they are inversely proportional to the weight per foot of the mooring line material. B) The ground cable for the heavier chain would be longer, not shorter, compared to the wire rope. C) The ground cable lengths can be determined based on the given information about the mooring line weights.
