Which limitation manifested structurally when medieval rope bridges experienced increased use?

💡 Explanation

Increased sag occurs because medieval rope bridges primarily used plant-based fibers, and creep led to permanent deformation under constant tensile stress, therefore the bridge sagged over time rather than maintaining its initial geometry.
