What can occur when a rope is suddenly put under unusual tension?

• A. Shock load
• B. Elastic rebound
• C. Prolonged stretch
• D. Slippage

Answer: (A)

When a rope is suddenly put under unusual tension, a shock load occurs. This is a brief but very high peak force that happens as the moving mass and gear are abruptly decelerated. The rope’s inertia and the equipment in the system mean the actual force exceeds the static load, which is why dynamic loading is a critical consideration in rescue and climbing scenarios. Elastic rebound is about the rope snapping back after being stretched, not the sudden spike in tension. Prolonged stretch describes creep under a sustained load, not a sudden event. Slippage involves rope moving through hardware, which is a separate issue from the surge in force. The core idea is that the sudden jerk creates a transient, higher-than-usual force—the shock load.
