Lay refers to what aspect of a wire rope?

• A. The material of the rope
• B. The length of the rope
• C. The way the strands are wrapped in the rope
• D. The protective coating

Answer: (C)

In wire rope, lay describes how the strands are wrapped around the core, including the direction and pitch of the twist. This arrangement determines how the rope behaves under load—its flexibility, tendency to rotate, how it wears on sheaves, and its fatigue characteristics. You can have different lay types, such as right- or left-hand lay and regular lay versus lang lay, which change how the strands braid around the core.

The other options refer to different rope properties: material is what the rope is made of, length is a measurement of size, and protective coating is an outer treatment—none of these describe how the strands themselves are arranged inside the rope.
