One of these war machines was the onager, a small catapult used by the Roman Army during the Roman Empire. At that time, precise rules for constructing catapults were developed, strictly observing the mutual proportions of their individual elements, based on the results of experiments.

The ballista was created by the Greeks, and was later modified by the Romans. The second type of latch would be attached between the beam arm and the ropes of the windlass (see siege engine mechanics) There is no catapult that is the best at everything. What advantages did catapults have? To fire it, the spoke or arm was forced down, against the tension of twisted ropes or other springs, by a windlass, and then suddenly released. In order to fire a projectile, the arm was pulled back, almost to a horizontal position and attached to a rope that acted as a trigger.
