WM2D Programme bug or new phenomenon?

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.
