Question
History

On Viking longships crossing fjords, which risk increased substantially if the rope bridge maintaining structural integrity became waterlogged from prolonged submersion?

A)Increased catenary sag and instability
B)Elevated corrosion rate in salt air
C)Bridge-deck induced shear stress increase
D)Reduced cable splice tensile capacity

💡 Explanation

Moisture increases the weight on a rope, causing catenary sag and additional deck instability because the suspended structure is weakened; therefore, sag develops easily and becomes more sensitive to shifting loads, rather than a concern about corrosion at a higher location.
