Which risk increases when early cast-iron cannons experience internal defects during the gunpowder ignition?

💡 Explanation

Rapid barrel rapture happens because internal defects weaken the cast iron, thus the pressure during powder ignition exceeds the materials limited tensile strength forming cracks that propagate; therefore barrel splits violently rather than just deforming or misfiring
