Which material options can serve as the center core of a wire rope?

• A. Steel or Nylon
• B. Fiber or Wire
• C. Copper or Aluminum
• D. Kevlar or Glass

Answer: (B)

The center of a wire rope is called the core, and its role is to provide a stable baseline around which the strands wind, influencing flexibility, strength, and how the rope behaves under load. The two standard core options are a fiber core or a wire core. A fiber core uses natural or synthetic fibers to keep the rope flexible and absorb some loading, while a wire rope core is a smaller wire rope placed inside to add stiffness and strength. This is why “Fiber or Wire” is the best answer: it captures the common core types used in wire rope construction. The other materials listed aren’t the standard core types. Steel as a center would make the rope very rigid; nylon, while a synthetic fiber, isn’t the conventional way to classify the core in typical rope constructions; copper or aluminum are metals not used as the primary center core in standard wire rope; Kevlar or glass aren’t the usual core options in conventional rope design.
