Which mechanical consequence resulted from rapid catapult arm deceleration upon projectile release during Roman siege warfare?

💡 Explanation

When the catapult arm rapidly decelerated, significant inertial forces generated stress concentration because of constrained movement, causing stress fractures around the arm pivot point. Therefore, pivot fractures more likely resulted, rather than torsion fiber compaction, velocity increase, or recoil reduction, which are associated with entirely different mechanisms and components within the machine.
