.....if we take into consideration a variable arm (alike a marble rolling off a bowling ball...) , at :
     http://crbond.com/physics.htm
     due to the gravity free fall and the rotational inertia possible" elongation" of the arm
.....and the throwing /long-short hinged arm ,as :
     https://youtu.be/Yca2m5PTP7A  ...a so old design , but let's play a single hinged arm , as :
     https://commons.m.wikimedia.org/wiki/File:Trebuchet_Scheme.png  , a so old simple machine
     https://youtu.be/qTK8YEK4kuk ...a new design , but let's play the "old" 180* "restriction" ...
     Here is a great difference between the old "knee joint" and the new "free joint", if we intend to control the hinged arm..."via" gravity.

You can a diversity of lever arrangements ( Class 1,2 or 3)...

There are better designs now. The Swivel Lever Device and V Lever and Escher Lever have more evidence now, relatively easy to build partial models.
