Which risk increases when a historic Inca suspension bridge's fiber ropes experience repeated loading?

💡 Explanation

Fatigue failure risk increases because repeated loading concentrates stress, leading to fiber weakening, therefore material fatigue accelerates cable degradation by crack propagation, rather than changing the load distribution causing tower collapse.
