Transcript
00:00Roman legionaries smash ancient stone bridges simply by walking across them together.
00:06Thousands of heavy boots striking the ground in unison generate identical mechanical vibration waves.
00:14These synchronized footfalls match the natural frequency of the heavy masonry span perfectly.
00:20The amplified kinetic energy builds inside the rock until structural fracture tears the bridge apart.
00:27Harmonic oscillation amplifies structural fatigue until masonry arches fracture under boots.
