Which increased risk resulted from repeated pedestrian crossings overloading early rope bridges?

💡 Explanation

Early rope bridges lacking modern tensioning experienced heightened cable tensile fatigue, because cyclic loading strained the material. Therefore, ropes degrade faster leading to breakage, rather than deck slip, wind resonance or pier scouring, which affect completed structures.
