Which consequence resulted from improperly annealed casting during manufacturing of Roman pila?

💡 Explanation

Improper annealing in the pila manufacturing leads to residual stresses. Because of the material's weakness, increased stresses lead to yielding under impact: this is stress-strain-failure rather than shattering, corrosion, or weight reduction.
