Using a wire rope with more wires in a strand increases which property?

• A. Tensile strength
• B. Weight
• C. Flexibility
• D. Abrasion resistance

Answer: (C)

Increasing the number of wires in a strand makes the rope more flexible because it becomes a bundle of many small, interwoven elements rather than a single rigid strand. Each wire can bend and slide independently within the strand, so the overall assembly can bend around pulleys and through tight passages more easily. This added bendability is especially valuable in applications where the rope must curve frequently or sit on sheaves. Tensile strength relies mainly on the total cross-sectional area of metal and the material's strength, so simply adding more wires in a strand doesn't inherently boost breaking strength and can add weight. Abrasion resistance depends on surface wear dynamics and construction details rather than just the number of wires, so it isn't the direct outcome of increasing wires per strand. The clear, consistent effect described here is the greater flexibility.
