What are the two classes of Kernmantle Rope?

• A. Dynamic (High stretch, recreational climbing rope)
• B. Dynamic and Static
• C. Static rope only
• D. There are no distinct classes

Answer: (B)

Kernmantle rope is categorized by how much it stretches under load. That distinction gives us two classes: dynamic and static. Dynamic ropes are designed to elongate when loaded, so they absorb energy from a fall, which helps reduce the peak forces on the climber. Static ropes have very little stretch, making them ideal for tasks where you want a stable, predictable line—like rope access, hauling, or controlled descents—without the extra “give” that a fall would cause. The question’s best answer reflects this dual-class idea: there are two classes, dynamic and static.
