Which component accounts for about 80% of a kernmantle rope's strength?

• A. The Mantle (sheath) accounts for 80%
• B. The Outer cover
• C. The Kern (core)
• D. The Full rope

Answer: (C)

In kernmantle ropes the load-bearing strength comes mainly from the kern, the inner core. The sheath (mantle) wraps around the kern to protect it from abrasion and wear and to help with handling, but it carries far less of the load than the core. Typically, about 80% of the rope’s strength is provided by the kern, with the sheath contributing the remaining portion. So the kern (core) is the component responsible for about 80% of the strength. The sheath (outer cover) is important for protection, not for most of the strength, and the full rope is the combination of both parts working together.
