Which outcome results when inadequately anchored cable bridges experience excessive wind loading?

💡 Explanation

Resonance occurs if wind excites the bridge's natural frequency; therefore, increasing the oscillating amplitude via positive feedback leads to structural failure, because increased stress exceeds material's load capacity, rather than a gradual material yielding at lower frequencies.
