Which mechanical risk increased for Ancient Mesopotamian chariots when bronze wheel bushings experienced significant wear?

💡 Explanation

When bronze bushings wear, the increased radial clearance allows greater friction. This leads to increased radial force between the wheel’s axle and its supports reducing rotational effectiveness and potentially axle seizing. Therefore, the risk of axle seizing increases, rather than chassis cracking, wheel detachment or rim fracturing, which involve different wear patterns or failure modes involving distinct constraints.
