Why is 6X19 class wire rope more commonly used for cargo runners than the more flexible 6X37 wire rope?

Correct Answer: Option B — It resists abrasion better.

Wire rope constructed in the 6x19 class contains fewer, thicker outer wires compared to 6x37 rope. This design provides superior resistance to external abrasion and wear encountered during heavy cargo handling operations, outweighing the benefit of extra flexibility.
