← HistoryWhich risk increases when ropes of a Viking rope bridge experience extended periods of high humidity plus submersion events?
A)Rope's tensile strength greatly decreases✓
B)Deck planks undergo rapid expansion
C)Anchorage stones lose cohesion
D)Supporting towers suffer foundation collapse
💡 Explanation
Excessive rope water absorption leads to fiber damage due to hydrolysis: ropes weaken. Rope strength sharply diminishes because moisture promotes breakdown, therefore the whole structure becomes unstable, rather than primarily affecting secondary elements or the foundation.
