Which materials failure limited Bronze Age gear mechanisms?

💡 Explanation

Bronze gears suffered galling because adhesive wear transfers material due to high contact pressure between teeth; the lack of effective lubrication exacerbated this mechanism. Therefore, galling was limiting, rather than the other options that are relevant for static bronze parts.
