Question 1591Deck General70% to pass
Close link chain of not less the 3/4" (or the wire rope equivalent) is required for lashing deck cargoes of timber. What size flexible wire rope would provide the strength equivalent to 3/4" chain, using a safety factor of 5?
AI Explanation
The correct answer is B) 1".
According to U.S. Coast Guard regulations, the minimum size of flexible wire rope that can be used as an equivalent to 3/4" chain for lashing deck cargoes of timber is 1" diameter, using a safety factor of 5. This ensures that the wire rope has sufficient strength to safely secure the cargo, as required by the regulations.
The other options are incorrect because a 9/16" wire rope (choice A) would not provide the necessary strength, while 1 1/4" (choice C) and 1 3/8" (choice D) would be larger than the minimum required size.
