Which risk increases for suspension footbridges when high winds induce resonance?

💡 Explanation

Catastrophic failure increases because increased frequency excites the bridge's natural frequency; therefore the amplitude sums via constructive interference to induce aeroelastic flutter, rather than stay minimal owing solely to dampening from cables.
