Another Model with Excess Weight on the Descending Side

Description

A silux model with three times more weights descending than ascending

Here is a screenshot of a silux model that has a large excess of weight on its descending side; one of the last that I made in my own investigations of this approach. Like the physical model in my blog post of 3 April 2014, this one has two axles, represented by the two fixpoints in the center; one at the origin, and one displaced 0.05m to the right.

All of the twelve "left" weights (black) are attached to and can pivot about the left axle, at a radius of 0.4m. All of the twelve "right" weights (red) are attached to and can pivot about the right axle, at a radius of 0.45m. All weights have masses of 4kg. Gravity is activated.

The compression springs between the weights are all the same, with natural length 0.3m and minimum length 0.02m, at which maximum force is 2000N. (Giving k = 7142.86N/m).

The dividers, 0.05kg each, pivot about the left axle, and keep the model stable, preventing the weights from going past each other when they close up on the descending side.

Results

One of the design aims with this model was to find a geometry that would cause many of the springs between the descending-side weights to compress significantly, thus allowing many weights to become "close-packed" on that side. At least that design aim was achieved.

This model does not depend on any mass-spring resonance, and although there are three times as many weights on the descending side as there are on the ascending side, the configuration shown is actually the equilibrium state for this model. It will not move out of this state unless energy is added, proving that a large excess of descending-side weight is not a sufficient condition, by itself, for perpetual motion.

Although I have made many more silux models, I don't propose to discuss any more of my own ideas for a while. In the next few blog posts I'll look at some other inventors' ideas.
