Which outcome occurred if Bronze Age Mesopotamian chariots exceeded copper's fatigue limit during warfare use?

💡 Explanation

When copper axles experienced cyclical stress exceeding fatigue limit, crack propagation occurred because repeated loading weakened the material over time, leading to sudden failure. Therefore axle fracture results, rather than wheel detachment, chassis warping, or bent frames which demand fundamentally different physical or chemical mechanisms.
