← HistoryWhich consequence resulted from rope bridge failure under Zhang Heng’s seismoscope?
A)Loss of crucial directional stability
B)Disrupted mercury ball triggering✓
C)Increased structural support resonance
D)Created harmonic mechanical instability
💡 Explanation
Seismic waves displace the rope supports; the resulting oscillation dampens the already sensitive trigger mechanism, because the **dampened oscillations** disrupt the free movement of the mercury balls needed to activate the drop. Therefore functionality decayed rather than providing valuable resonance data.
