Which risk escalates with continued swinging motion in historical rope bridges?

💡 Explanation

Strand fretting fatigue increases because cyclic localized stress leads to micro-cracks weakening the cable material. Therefore, cable failure becomes more probable rather than simple tensile overload or global bending, which are less sensitive to dynamic motion when loads increase over time.
