Which structural weakness limited the maximum scaling size of Roman ballistae for siege warfare?

💡 Explanation

As ballistae scaled up, the compressive forces on the wooden frame joints increased, because force and dimension interact in complex loading scenarios, raising the risk of buckling instability. Therefore buckling caused by frame joints give way, rather than iron fatigue, rope failure or inertia dominating, all of which depend on other materials or dynamics.
