How Climbing Ropes Absorb the Force of a Fall

A dynamic climbing rope stretches during a fall, increasing stopping time and reducing peak force. The episode explains the physics and standardized testing without offering climbing or safety instruction. Inside this episode: - The problem is stopping - A rope with a core and sheath - Energy moves through a system - The drop test - Stretch is controlled, not limitless Sources include The ideal dynamic climbing rope, UIAA 101 Dynamic Ropes, and UIAA 110 explanatory note.
