Which vulnerability increased in torsion-powered Roman siege engines during prolonged rain?

💡 Explanation

During rain, moisture absorption causes fiber swelling in twisted ropes which reduced tension. This compliance change alters the stored energy because release of tension results in lower strain on the projectile. Therefore projectile range decreases as tension slackens, rather than frame failures, targeting obstructions, or gear problems which occur from other mechanisms.
