What is the rated capacity of 7/16 in nylon rope?

• A. 3,180 lbs
• B. 4,500 lbs
• C. 11,000 lbs
• D. 25,000 lbs

Answer: (B)

In rope use, the rated capacity is the working load limit—the maximum safe load you should apply, not the rope’s breaking strength. It’s established by taking the rope’s minimum breaking strength and dividing by a safety factor to account for shock loads, knots, wear, and other real‑world effects. For a 7/16 inch nylon rope, the typical breaking strength is around 22,500 pounds. Using a safety factor of 5, the working load limit becomes 4,500 pounds. This is why 4,500 pounds is the rated capacity: it represents a conservative, safe operating limit rather than the rope’s absolute breaking point. The other numbers reflect either the breaking strength or different, less appropriate safety factors, which is why they don’t represent the recommended working load.
