← HistoryWhich destructive mechanism allowed Roman siege engines, like the 'Onager', to breach fortified walls?
A)Kinetic energy transfer from projectile impact✓
B)Chemical reaction from incendiary ammunition
C)Acoustic resonance shattering stone blocks
D)Electromagnetic pulse weakening metal reinforcement
💡 Explanation
When a projectile impacts a wall, kinetic energy transfer occurs because the projectile mass and velocity convert into force against the structure, leading to material failure and cracking. Therefore kinetic energy transfer results, rather than chemical reactions, acoustic resonance or EMP, which require different mechanisms and projectiles.
