Which property best describes a factor that reduces elongation in Kernmantle rope?

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

Answer: (C)

Reducing elongation means choosing a rope that doesn’t lengthen much when a load is applied. Kernmantle ropes come in dynamic designs, which are built to stretch a lot to absorb impact, and static or low-stretch designs, which elongate very little. If you want to minimize how much the rope lengthens under a given load, a rope with low stretch is the clear fit. High stiffness mainly describes resistance to bending rather than the amount the rope can extend under load, so it doesn’t directly control elongation. Low cost doesn’t indicate how much the rope will lengthen when used. So, the factor that best describes reducing elongation is low stretch.
