What is the breaking strength of 7/16 inch nylon rope?

• A. 550 lbs
• B. 3,180 lbs
• C. 80 lbs per wrap
• D. 4,500 lbs

Answer: (D)

Breaking strength is the maximum load a rope can carry before it fails in a straight pull. For nylon rope, the published breaking strength scales with diameter, and a seven-sixteenths inch rope is typically rated around 4,500 pounds. That’s why 4,500 pounds is the best answer: it reflects the standard tensile capability of nylon at that diameter. In real-world use you’d apply a safety factor to determine a working load limit, but the breaking strength itself sits near 4,500 pounds for this size. The other options don’t fit because they’re either far too low for this diameter or refer to a different, non-breaking-load measure.
