What causes rope failure?

What causes rope failure?

• A. abrasions
• B. kinks
• C. UV exposure
• D. Water absorption

Answer: (A)

Rope failure most often begins with wear from friction. When rope slides over rough surfaces, hardware, or sharp edges, the outer sheath and the individual fibers rub away. This abrasion removes material and creates micro-cracks that propagate under load, weakening the rope until it can no longer hold or fails suddenly. Other factors like UV exposure, water absorption, or kinks can contribute to degeneration or localized damage, but they don’t directly and consistently cause failure as quickly or predictably as abrasion does. So, the primary cause among commonly cited mechanisms is abrasion, because it directly degrades the rope’s structural fibers through repetitive wear.
