Which risk notably increased as suspension bridges lengthened during development?

💡 Explanation

Harmonic resonance became a greater problem; small oscillations caused positive feedback, eventually leading to collapse, because its frequency matched the bridge's natural frequency. Therefore, understanding aeroelastic flutter was important, rather than just load calculations.
