← HistoryWhich risk increases in Inca suspension bridges during high winds?
A)Deck oscillations become catastrophic✓
B)Quipu communication systems fail
C)Stone anchor slippage intensifies
D)Rope deterioration accelerates locally
💡 Explanation
Catastrophic deck oscillations become likely because high winds induce a resonance effect, a form of forced vibration with increasing amplitudes. Therefore, the bridge loses structural integrity rather than other localized failures that would occur under static loads. .
