Which characteristic is NOT associated with fiber core rope?

The characteristic that is not associated with fiber core rope is increased strength. Fiber core ropes typically do not exhibit the same level of strength as ropes that utilize other materials, such as wire or synthetic cores. In the context of rope construction, fiber core ropes are designed with fibers that provide flexibility and lightweight properties, allowing for easier handling and versatility in various applications.

The basic construction of fiber core ropes involves fibers being twisted together, which contributes to their lightweight nature but also means they may not possess the high strength levels when compared to other core materials. Thus, while fiber core ropes have positive attributes such as lightweight and flexible characteristics, claiming increased strength as a feature would be inaccurate.
