This time,the two swinging sticks game has:
-a fixed fulcrum
-a mobile game
-a rotatio limiting point for the small stick
It can be a starting image to think about and evolve the topic of this forum.

Hi !
Generally speaking,a fulcrum is the support of a body,inside/on the surface of another body.
The topic about swinging sticks implies a long serial (shadouf,country water well,...Milkovic's lever with pendulum....desk toys /lever+pendulum+magnet+battery).
All have on paper ,a simple prime line: fulcrum+lever/long stick + pendulum or counterweighted pendulum/small stick).
This is my point of view to simplify the way to a possible PM device.
Mobile fulcrum is a more general problem : a flexible body insile an elastinc medium ("fish in water" and still more...).
If the fish undulates,the water reacts as that to a slippery air "intrusion":there is no difference for the "point of view" of the liquid medium.
As you can see,there are two separate topics/concepts that can help one another...
