Which attribute is improved by increasing the number of wires per strand?

• A. Flexibility
• B. Cost
• C. Weight
• D. Corrosion resistance

Answer: (A)

Flexibility is improved when you increase the number of wires per strand because smaller wires can bend more easily than a single thick wire. When many fine wires make up a strand, each wire can flex a little on its own as the rope curves or passes over pulleys, distributing bending more smoothly and reducing stiffness. The overall rope becomes more pliable as a result. Cost and weight aren’t the attributes that typically benefit from more wires per strand, and corrosion resistance isn’t inherently improved by simply changing the strand’s wire count.
