wrong thread.
Fulcrum of the three-armed rotor does not move. It does not apply weight to the large rotor. It won't work.
Rotation of the wheel places tension on the axle
of the smaller spindle.

It actually has millions of uses, to apply torque and leverage
Design complex actuators
Archimedes wrote an entire book of these things.
But they do require energy to operate.
Hmmm, so does the Archimedes thing have a true circular path around a center? Makes me want to try something if it does.
At certain points yes, at others the path varies slightly from Pi
depending on the design of the contraption
And this causes slight friction and pressure on places.
Some designs are more Pi-ish than others.
A lot also has to do with precision, and clearance of the moving parts
Watched it more closely in slow mo and it is really an oval path. Not workable for me. Onward.
