According to the described wire rope terminology, lang lay rope strands run in which orientation relative to the rope?

According to the described wire rope terminology, lang lay rope strands run in which orientation relative to the rope?

• A. Perpendicular to the rope
• B. Parallel to the rope
• C. Diagonally across the rope
• D. Winding around the core

Answer: (A)

Lang lay describes how the strands are laid in relation to the rope’s axis. In lang lay rope, the wrap pitch is longer, so the strands wrap around the core at a gentler angle and run more along the length of the rope. In other words, the strands are parallel to the rope axis rather than crossing it at a sharp angle. This makes lang lay rope more flexible and easier on bends and sheaves. The other orientations don’t match how lang lay strands actually sit relative to the rope: they’re not perpendicular or diagonally angled across the rope, and simply “winding around the core” describes the overall construction, not the strand direction along the axis.
