Which consequence occurred when Roman siege engines targeted city walls using torsion springs beyond their design limits?

💡 Explanation

Catastrophic frame structural failure from overtensioning occurred in torsion-powered siege engines, because excessively high torque exceeded material strength, causing disintegration through bending stress. Therefore, frame failure was the result, rather than maintaining accuracy or velocity at extreme torsion levels.
