Which maintenance outcome was necessitated by the high static load in a medieval stone siege engine’s (trebuchet) frame?

💡 Explanation

Medieval trebuchets experienced timber degradation requiring frame replacement, because creeping caused increased strain, triggering crack propagation; excessive stress concentrated wood fibers, therefore leading to failures rather than other adjustments, which could mitigate but not prevent timber damage.
