Which outcome most immediately impaired the structural integrity of besieged castle walls bombarded by Roman stone throwers (ballistae)?

💡 Explanation

Repeated bombardment causes material fatigue, because microscopic crack accumulation increases dramatically impacting structural durability, therefore sudden wall collapse is more likely, rather than immediate shattering or melting, which request energy or chemical alteration.
