Which risk increased when Roman siege engines fired heated projectiles?

💡 Explanation

Firing heated projectiles caused creep in metal components because the elevated temperature lowered the material's elastic modulus. Therefore, the tensile strength declined rather than atmospheric effects or crew risks being the primary concern under controlled firing conditions.
