Which risk arose when using torsion catapults to hurl incendiary projectiles at wooden fortifications?

💡 Explanation

When launching incendiary projectiles, the risk of premature ignition is significant because friction and compression within the torsion bundles of the catapult could generate heat, directly igniting the ammunition before launch. Therefore, premature ignition is more relevant than rope failure, aiming errors, or wind effects which affected all projectiles equivalently.
