Which outcome results from repeated heating and cooling of bronze cannons during 18th century naval battles?

💡 Explanation

When bronze cannons undergo thermal cycling, differential expansion induces stress because different parts of the barrel heat unevenly, leading to plastic deformation. Therefore barrel warping results, rather than explosion, trunnion failure, or obstruction which require propellant defects, excessive recoil, or projectile flaws.
