The wheel on the bottom of the catapult which is the large diameter disk obtains the load force being launched from the catapult. The axle which is the small diameter shaft (the spoke that is used to attach one tire to the other) also helps to move the both wheels to once again support the heavy load being launched. Basically, the wheel and axle have 2 jobs to preform in a catapult. The first one is to obtain the heavy force pushing down from the catapult. The second one is that it helps move the catapult from one place to another. For example, back in the medieval when they used the catapult constantly in wars they couldn't just stay in the same stop expecting they wouldn't get killed from the enemy. They had to move themselves and there catapult using the wheel and axle.
Levers and pulleys also work in the catapult. The lever is the catapult arm. The the pulley is the rope being pulled down to tie the rope down for an attack to be launched.
I hoped I helped! The funny thing is that I searched up this answer and when I clicked on this I found nothing so I decided to write something. I guess I actually didn't need to search this question up in the beginning.
