Объяснение
Both engines stored energy mechanically and released it to hurl a heavy projectile on a high curve, and the larger of the two drove its arm by letting a weighted beam fall. Calling such an engine a giant crossbow fails because that describes a different weapon which shoots a bolt flat along a groove rather than lobbing stone shot over a wall.
