Okay so I found this:
In modern archery, a compound bow is a bow that uses a levering system, usually of cables and pulleys, to bend the limbs. ... The pulley/cam system grants the user a mechanical advantage, and so the limbs of a compound bow are much stiffer than those of a recurve bow or longbow.
Pls give me brainliest if I helped!
Have a great day <33
