What type of rope is designed to be elastic and stretches when loaded?

Dynamic rope is specifically engineered to be elastic, allowing it to stretch when subjected to a load. This characteristic is crucial for climbing and rescue operations, as it helps to absorb the impact forces generated during a fall. The elasticity of dynamic rope minimizes the potential for injury by reducing the amount of force transmitted to the climber or user, allowing for a safer experience during high-stress activities.

Static rope, in contrast, is designed to have minimal stretch, making it ideal for situations where elongation could be detrimental, such as rappelling or rescue scenarios where stability and control are paramount. Twisted rope refers to the manufacturing process of the rope and does not specifically indicate elasticity. Kernmantle rope is a type of construction that includes a core (kern) and an outer sheath (mantle), which can be either static or dynamic. However, it does not imply that the rope itself is elastic.
