Which vulnerability increased effectiveness in Roman torsion siege weapons?

💡 Explanation

When organic fibers are torqued in siege engines, humidity fluctuations weaken the fiber matrix, inducing progressive slippage and creep because moisture reduces interfiber friction and alignment. Therefore increased fiber degradation results which permits catastrophic failures providing unpredictable ranges, rather than instability, slippage problems, or bearing alignment errors requiring distinct engineering issues.
