Which challenge dictated the design of single-rope pedestrian bridges (rope-slide bridges) used in pre-modern Andean cultures?

💡 Explanation

Rope-slide bridges demanded minimal rope span and load because *elastic extension* reduced lift capacity under tension more than minimizing vibration, therefore their length was heavily constrained rather than designed for aerodynamic stability.
