History

Which outcome accelerated medieval castle wall destruction from cannon fire?

A)Kinetic energy to stress waves
B)Moisture weakened mortar joints
C)Torsion spring stress accumulation
D)Shear stress on foundation stones

💡 Explanation

Castle walls rapidly succumbed to cannon fire thanks to the kinetic energy transfer to stress waves. These stress waves initiated cracks throughout the structure because the brittle stonework was unable to effectively dissipate energy; therefore, catastrophic failure occurred via fracture, rather than simple local spalling.
