##### Is it possible to increase the potential energy of this device ?
« on: 26/07/2015 12:58:12 »
Hi :)

A square red object has a lot of balls inside it. There is a part where there is no ball because after I will use a torus. One spring attrack one ball and balls are very small. There are 2 areas inside the square object, the upper where the attraction is higher than in the lower part ( attraction1 > attraction2 ). With springs, I create pressure like water in a recipient under gravity. I drawn only 3 springs and I did not draw all green points. The square object receives the forces F1, F2 and F3 from the springs, I did not draw all forces. The forces F4, F5, and F6 come from the pressure of the balls at the right side. The forces F7, F8 and F9 come from the pressure of the balls to the left side. It's logical the square object receives a counterclockwise torque. The Area1 (attraction1) and Area2 (attraction2) are not connected, pressures are not the same.

I tried following your post but it was too confusing. I'll try again later. But the general answer to your question is yes. If you do work on a system then the potential energy of the system increases. E.g. suppose you were to compress a spring and then tie the string in the compressed state. The potential energy of the spring system increased as a result.

I would like to understand for this device because the square object increases its potential energy without an external power. I need an energy for accelerate the torus but I can recover this energy later. The square object receives a torque from balls but the torus not. The square object will accelerate but I accelerate the torus in the same time, like that the position of the square object is always the same in the reference of the torus. Maybe ask me questions about the device like that I can reply with simple sentences.
The only way to increase the potential energy of a system without doing work on the system is to convert some of the other forums of energy in the system to potential energy.

I would like to understand why my device cannot work. I made an error somewhere but I don't find where, could you help me ?
I wish I could but I can't understand what you wrote. It's too confusing for me. E.g. you talk about pressure but you don't tell me what the source of the pressure is. You talk about attraction but don't say what the source of attraction is. You're not clear as to what the purpose of the torus is either. You give no clear reason what the source of the forces F1, F2 etc. are either. I can go on and on but basically its extremely confusing. I have no idea what you're trying to do and why. So if I can't for the life of me understand what this is all about how could I even begin to help you?

Perhaps someone will be willing to decipher all of this and help you. Not me though. Sorry.

If it was simple to understand I would never have been confused. I'm a very bright and have a very sharp mind. I don't miss a trick. But your diagram and explanation was very confusing. And I simply won't make anymore attempts to decipher it. Sorry. No offense.
