Which risk most directly increases when early rope suspension bridges experience diurnal moisture changes?

💡 Explanation

Tensile strength aging increases because diurnal moisture ingress in natural fiber ropes leads to hydrolysis. Hydrolysis weakens polymer bonds within the rope fibers, therefore tensile strength diminishes irreversibly, rather than affecting the bridge structure directly because hydrolysis impacts strength at the material level.
