← HistoryWhich risk increases when a historical rope bridge undergoes excessive wetting?
A)Accelerated catenary support failure✓
B)Pylon anchor slippage increases
C)Deck plank delamination occurs
D)Increased wind vortex shedding
💡 Explanation
Catenary failure risk increases in hemp rope bridges with excessive wetting cycles because moisture weakens the constituent fibers via hydrolysis, therefore tensile strength decreases, rather than causing anchor slippage which would require detachment of physical lashings.
