Across simplistic rope suspension bridges, which increased risk resulted when maintaining tightly packed infantry formations?

💡 Explanation

Transverse vibrational resonance is amplified because marching infantry induces rhythmical forces matching structure's natural frequency. Therefore, amplitude grows until bridge collapses rather than simple cable sagging, because rhythmic input excites resonance.
