Ok, here it is.
The left arm has the weight at the center producing a force downward F, and the right arm has an equal force (weight) displaced to the right along the horizontal arm.
The figure on the right shows the equivalent forces acting on the balance to the figure on the left, namely, the force on the right is shifted back to the center and the moment it created is shown.
Now, the two forces at the centers balance themselves out, should be easy to see.
But, the torque is not balanced and will it not rotate the balance until the top and bottom arms are horizontal, at which point it is balanced, this is the neutral point we were shown in the video, but in the rotated position I have drawn it, there is a restoring torque which should be easy for anybody to visualize.
Therefore, all we have to do is have a synchronizing mechanism to shift the weight at the opportune moment, to constantly create rotation and torque.
Is that not it? Even if the torque can't rotate the balance, I think we can still make use of this dual pivot parallelogram balance in the Bessler wheel. This is great stuff! or is it? lol
