Which structural weakness was primarily exploited by siege engines against medieval stone fortifications?

💡 Explanation

Siege engines like battering rams primarily worked by applying concentrated force that induced tensile stress along mortar joints, causing the joints to fail and stones to separate. Therefore, tensile stress along mortar joints was exploited, rather than shear in arches, compression in blocks or torsion, which require different distributions of force and failure planes.
