Wire rope strands are laid around a central core of either IWRC or what?

• A. Fiber
• B. Steel
• C. Plastic
• D. Composite materials

Answer: (A)

The correct answer is that wire rope strands can be laid around a central core of fiber. In the construction of wire rope, a core is essential as it provides structural support and helps maintain the shape of the wire. The fiber core is typically made from materials such as natural fibers or synthetic materials, which can absorb shock and improve flexibility, contributing to the overall performance of the rope. This type of core is often used in applications where weight reduction and easier handling are priorities.

While other materials like steel, plastic, and composite materials might be used in various types of constructions, the focus here is specifically on traditional wire rope construction, where fiber serves an important role, especially in applications requiring a lightweight and flexible cable.
