Which destructive outcome resulted when Roman siege engines persistently struck a castle wall at its base,?

💡 Explanation

When Roman siege engines persistently struck a wall's base shearing stress occurs because the repeated force applies a tangential load, exceeding the material's shear strength, leading to crack propagation and eventual collapse. Therefore, shearing stress exceeding material limits results; resonance, buckling and fatigue focus on entirely different aspects of structural failure.
