Which type of rope has minimal stretch under load?

The type of rope that has minimal stretch under load is static rope. Static ropes are designed specifically for situations where minimal elongation is crucial, such as in rescue operations, high-angle rescues, and when anchoring. This characteristic allows firefighters to maintain stability and control, ensuring safety when working at heights or in potentially hazardous environments. Static ropes are constructed with a tight weave and are usually made from materials that offer low stretch, making them ideal for climbing, rappelling, and securing equipment without the risk of unexpected elongation.

Dynamic ropes, on the other hand, are designed to stretch to absorb the shock of a fall, which is essential for climbing activities but would not provide the required stability for certain firefighting applications. The terms fixed and pliant do not specifically refer to rope types with defined stretch characteristics, making them less relevant for situations where minimal stretch is a priority.
