Which risk increases when a medieval trebuchet bridge uses insufficiently lubricated capstan bearings?

💡 Explanation

An increase in friction of capstan bearings would reduce the stored energy released during launch, therefore lessening launch consistency, because increased friction wastes energy pulling back the projectile rather than going towards kinetic energy, rather than structural failure within reason.
