In a mountain-climbing technique called the "Tyrolean traverse," a rope is anchored on both ends (to rocks or strong trees) across a deep chasm, and then a climber traverses the rope while attached by a sling as in Fig. $102 .$ This technique generates tremendous forces in the rope and anchors so a basic understanding of physics is crucial for safety. A typical climbing rope can undergo a tension force of perhaps 29 $\mathrm{kN}$ before breaking, and a "safety factor" of 10 is usually recom- mended. The length of rope used in the Tyrolean traverse must allow for some "sag" to remain in the recommended safety range. Consider a 75 -kg climber at the center of a Tyrolean traverse, spanning a $25-\mathrm{m}$ chasm. $(a)$ to be within its recommended safety range, what minimum distance $x$ must the rope sag? (b) If the Tyrolean traverse is set up incor- rectly so that the rope sags by only one-fourth the distance found in $(a),$ determine the tension in the rope. Will the rope break?
In a mountain-climbing technique called the "Tyrolean traverse," a rope is anchored on both ends (to rocks or strong trees) across a deep chasm, and then a climber traverses the rope while attached by a sling as in Fig. 9-91. This technique generates tremendous forces in the rope and anchors, so a basic understanding of physics is crucial for safety. A typical climbing rope can undergo a tension force of perhaps 29 kN before breaking, and a "safety factor" of 10 is usually recommended.
