Newton's laws seemingly broken not by a rotating wheel but by a swinging seesaw

[raj]

See:

1. An asymmetric seesaw made up of two rectangular mass, one of 7x3 units length and one of 2x1 units length joined together at one end in the form of
L-shaped mass, on an offset horizontal, axle, swinging clockwise and counter-clockwise alternately, NEVER finding a point of rest, seemingly breaking Newton's laws of thermodynamics,

Raj,

I think the asymmetric shape of the object hides the center of mass (CoM). I think all you are seeing in the simulation is simple oscillation of a swinging mass

I watched your video and based on the left (Figure 2) and right (Figure 3) end points of the swing, I have calculated the angle of the line on which the CoM exists (see Figure 1) - it would be somewhere below the pivot point.
