Which rope has the greatest breaking strength?

Nylon is known for its high strength-to-weight ratio, which makes it an ideal choice for applications requiring strong and durable ropes. The tensile strength of nylon rope is significantly higher than that of other natural and synthetic fibers. This property is particularly valuable in marine environments, where ropes must withstand heavy loads, abrasion, and varying weather conditions.

In comparison, while manila ropes are strong due to their natural fibers, they do not match the tensile strength of nylon. Polypropylene and polyethylene also do not offer the same level of strength, as they are often lighter and less durable under tension. Therefore, nylon’s superior breaking strength makes it the best option among the choices provided.
