Question 1591 Deck General
70% to passClose 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?
A
9/16"
B
1"
C
1 1/4"
D
1 3/8"
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.
