It relied on a torsion (twisting) to provide the energy for the throw, as opposed to a counterweight.

The exact first person ever to construct a catapult is unknown, however, the first civilisation to use the catapult was Rome, who designed catapults as siege weapons to aid in the expansion of its empire. The catapult was later adopted by other nationalities whowarred against each other.

The onager was a form of military catapult, and typically used stones as ammunition. It could also throw incendiary devices (intended to start fires). In some cases, dead animals were thrown in cities under siege, to damage morale, and to increase the chance of an outbreak of disease.
Like all ancient peoples, the Romans sued swords. They also adopted the Greek ballista and greatly improved on it. This was a crossbow-like catapult which fired darts.. There were large ones which were used for sieges and were carried on a wheeled wooden platform and there were small, handheld ones. In their later days they developed the onager, which fired boulders. Medieval catapults were modelled on the onager.
Type III Lever
They used the catapult for war.
To build a catapult that can fire a racquetball 7 meters, you can use a sturdy base, a lever arm, and a launching mechanism. Construct a triangular base for stability, attach a long lever arm to a pivot point, and use a strong elastic material (like a bungee cord) to provide the launching force. Position the racquetball in a cup at the end of the lever arm, pull it back to store energy, and release it to launch the ball. Adjust the angle of the arm and the tension in the elastic to optimize the distance.

No. Depending on how you use the wheel and axle changes what type of lever it is. If the wheel is turning the axle it is a second class lever. If the axle is changing the wheel, it is a third class lever.
