Which factor makes Kernmantle rope well-suited for rescues?

• A. Low friction
• B. Dynamic
• C. High cost
• D. High stiffness

Answer: (B)

Dynamic behavior is what makes Kernmantle rope well-suited for rescues. In rescue work, absorbing energy from a fall or sudden load is crucial to protecting the climber, rescuer, and anchors. Dynamic ropes are designed to stretch under load, so they lengthen a bit as force increases, which dissipates shock and lowers peak forces transmitted through the system. The Kernmantle design—a core that carries most of the load with a protective outer sheath—lets that energy absorption occur while still providing strength and durability. The other factors listed don’t address shock absorption or energy management in a rescue scenario, so they’re less relevant to why this rope type is favored.
