Sand watch on a swing

[Georg Künstler]

The red circle should represent a grain of sand. The grain of sand can fall on the same side of the swing, or if the sand watches are placed to short together on the ‘Wrong’ side of the swing, generating a turning moment.

It will be generate 2 times turning moment. One, because the grain is leaving the right side, and second, with a fall, delayed on the left side.

In all cases, the too short basic is generating the imbalance. This can be achieved with a grain of sand, balls, cylinders, water or magnets.

This mail is only to think about the overloaded, to short basic. Some of you shortly will find different ways to solve it.

I had to read it a few times, but I got it, sand-watch=hourglass. You are right that in the second picture there will be twice the torque that would be if there was only a grain of sand, and this is because there is an absence of the grain on the other side. To make it clearer, I've done a small drawing where the grain is big enough to notice the absence. It is a variant of Desaguliers' balance. The first part is balanced, and the second isn't. But I don't see how this leads to FE, because to restart after it has moved some amount, you must lift the little piece all the way back up to meet the rest of its block.

[Georg Künstler]

Obviously we can not manage to reach the start-point again. No way to get it overbalanced.
The one grain of sand, wherever we place it in our system, left or right, does not bring us the advantage of energy. So FE is not possible, Physicians get their right.

But now, we arrange the sand-glasses in a different way. On the left side of the swing, the sand should be down, on the right side the sand should be up. When we start dropping the sand on the right side, the swing is out of balance. As more sand is going down, as higher will be our turning moment on the swing. We are cancelling out energy on the right side, because one grain of sand hits another grain of sand, rolling this grain of sand side wards, jumping back, rotating etc.
So the drop energy on the right side is wasted.
We get a turning moment of the swing by wasting energy. As more we waste, as more we are out of balance.

A German proverb, saying is ‘in der Ruhe liegt die Kraft’. Maybe we should think about this proverb.

There is an unbalance, until that sand grain lands.

[Georg Künstler]

we can't get it in balance again, because the swing is now moving.

When you said that, it occurred to me that maybe I was wrong, that one weight falls straight and the other along a curve, so maybe they wouldn't gain the same momentum. But I built a model, and they do. When the grain lands, the whole thing stops and is balanced.

[Georg Künstler]

your model must be wrong. Sand watch = Hourglass. You must get a tuning of the swing if the hourglas is started. Only put a hourglass on one side of the swing as mentioned. The start energy left and right is not equal. m*g*h left is not equal to m*g*h right. How can it balance after started ? We lose energy and nothing will happen ?

I didn't use a swing. The problem is that if you use a swing, it will turn because it is top heavy, even if the sand grains do nothing. So I used the parallel beam device that I posted. Secondly, because I have no hourglasses, I noticed what is shown in the following attachment, that the green parts are pointless, so I got rid of them and used only two discrete weights, blue and red. The blue just sits there on the bottom platform, as shown. But I tied a thread to the red one and suspended it from the upper platform. Then I carefully burned the thread, so that the red weight fell and the blue weight started making the parallel beam device turn counterclockwise. Soon, the red weight landed on the the lower platform (which itself was moving up), and the impact ceased all motion and balance was regained. And to clarify, I made the space between the platforms much larger than is shown, and tried different lengths of thread.
EDIT Accidentally forgot the attachment...

[Georg Künstler]

so we are getting a turning moment or not. An accelleration of downfalling hour glas with the not moving sand on the left, or not.
It is only a very simple and cheap experiment, which showes us that in balance is not well balanced. Who is able to verify this experiment.

An hour glass with it's sand at rest will weight more on a set of scales than an hour glass with it's sand in motion (falling from top to bottom).

But what does this prove - any gain from the falling sand will be exactly cancelled by the effort required to reset the sand (lift it back) to it's original position. We already know that don't we?

[Georg Künstler]

yes, you know this function very well, but you don't use it in a wheel, why not ?, too simple ?

I will open the way of the one directional slow motional wheel in the next days under Georg's way to the one directional wheel.
