Illinois Rope Operations Practice Test

Nylon rope loses how much strength when wet?

5-7% 0% 20-25% 10-15%

Correct Answer:

10-15%

Explanation:

When nylon rope gets wet, it loses about ten to fifteen percent of its breaking strength. Nylon is hygroscopic, so water is absorbed into the fibers, causing a small reduction in stiffness and strength. This moisture effect means the rope can’t لللل as much load as when it’s dry, which is why the typical guideline falls in that 10–15% range. That’s why the best choice is the 10-15% option. The other figures aren’t accurate for nylon under common wet conditions.
