Which consequence resulted from flaws in Han Dynasty crossbow triggers?

💡 Explanation

Inaccurate cast-iron crossbow triggers introduce significant variation in sear release via the friction mechanism, because imperfect lever actuation modulates force during firing; therefore, projectile velocity varies at different rates, rather than offering consistent energy for predictable trajectories.
