WM2D Programme bug or new phenomenon?
« on: January 15, 2009, 12:18:54 AM »
G'day all,

I wonder if those of you who have WM2D would have a look at the following simulation.

The simulation shows 2 systems for comparison 1, a pendulum and 2, another pendulum suspended from 10kg beam which is free to move horizontally on rollers. The movement of the beam is restricted with springs.

The curious thing about it is, even though both pendula start with the same amount of potential energy and are identical in every respect, that the pendulum attached to the beam keeps moving long after the simple pendulum stops. There is a certain amount of air resistance programmed into the simulation to give a more realistic picture.

If the simulation is correct that would mean that there is more energy available in the beam type suspension than in the simple pendulum, which should be impossible.

Have a look and tell me what you think, this has me baffled.

Sorry guys, this is the wrong version that got uploaded twice, don"t know what happened there Here is the correct one, hopefully.

Edit, I just checked, this is the right one

Hello Hans,

I just noticed you are also using a polygon on rotators, would this simulation not suffer in the same way as the one you corrected for me?

I'm interested in the answer is no ..

Kind regards,

sweep.

EDIT: Correction, I should have said if the answer is no. Typo..

G'day Mindsweeper,

The triangle attached to the roller is simply a sensitive indicator of movement. If you click on it you will notice it has virtually no mass. You can take it off, the simulation does not change.

Hi Hans,

I had a good look at the simulation, not that I have any idea of what you are showing.

It looks to me like you have a nice store for the otherwise lost energy as in the static pendulum.

There was a thread about a guy who used a pendulum connected to a lever to produce what seemed to be a new phenomenon, perhaps this is a similar effect in that it harnesses the falling power of the pendulum in it's 1st half arc and then changes it's trajectory so the forces are not opposite.

How does it return to begin the second arc with energy left over compared to the static one is the question.

But then I could be totally barking up the wrong tree here and I've just made myself look foolish :)

Sweep.

I have a question about all of this computer modeling. Maybe it can help with visualizing a concept, but I am questioning the ability of a mathematical model to display a new or previously unknown property in a simulation.

A model must be programmed with KNOWN parameters. If a device has introduced a property that the programmer did not anticipate how can the model display the result of that property?

I am just a know nothing newbie, but I have to ask about the value of playing computer games instead of utilizing actual physical experiments.Could this time consuming activity actually be an impediment to new discoveries?

Are ALL of the properties of gravity known? If not, then how efficient can a model be in seeking unknown properties?

Not wanting to discourage anyone, but it would be unethical not to share this concern with others that are using modeling.

 :-\

Too many questions, and not enough answers!

You are absolutely right, of course. Nevertheless, it is interesting that within the same constraints two different results occur. I am just curious what is causing this. There are a number of bugs in WM2D and this is most likely one of them. However, only an experiment will tell for sure and it might just be worth doing.

@ mindsweeper,

You are thinking of the Milkovic device. This is actually something that cropped up when I investigated this particular thing. I simulated a number of variations along the idea of secondary oscillations. Have a look at the simulations below.

Hello Hans,

When I saw the Milkovic machine I thought it would not be long before someone managed to find the answer. I made simulations at the time and posited here with questions in relation but had very little interest. What I found daunting was the mathematics involved with the moving masses and wanted help.

As time passed I made many more simulations, I was so so sure there was something still hidden within the Milkovic device, after all he could hardly explain what he'd found. I made what little study I could and found myself drawn back to the CF side of things, then onto the law of falling bodies and how that could be applied. I'm now of the thinking that there is untapped potential in the unbalanced pendulum.

Hans, you are familiar with Bessler I'm sure, would it be possible to send you a simulation for evaluation? I'd rather not post for all to see.

sweep.

EDIT: Cant even get a name correct..
