Which maintenance problem frequently occurred due to material properties of Inca rope suspension bridges?

💡 Explanation

Accelerated cable creep was common in Inca bridges because plant-based ropes experience gradual, permanent elongation under tension from daily thermal cycling rather than brittle breaking. Therefore, sag increased over time, necessitating frequent replacement, rather than abrupt collapses.
