Which effect spurred changes in Chinese cast iron cannon construction after initial gunpowder era bursts?

💡 Explanation

Hoop reinforcement arose because thermal stress concentrations initiated cracks within cannon walls, leading to catastrophic failures. Metal banding provides compressive strength, therefore burst risks decreased, rather than breech mechanisms which addresses loading only.
