What's wrong with my idea ?
I try to have a torque on the black arm from forces of pressure. But I don't want this torque on the red arm. Do you understand the container with the balls+springs to obtain a pressure like the pressure with a liquid inside a container with gravity ? The only difference is at bottom, like I attract the balls and the part of the sphere inside the container, there is no force at "bottom" because the forces of springs are cancelled by the pressure of balls.
People once said it was impossible to go to the moon, ...
When laymen hear physicists state that something is impossible because it violates a law of physics, the layman almost always using that sort of argument. It's always wrong too because the people who made those claims weren't physicists.
The container has walls to prevent the balls to move outside. With a container full with water on a table on Earth there are pressure from the fluid at left, right, ok ? Like this example:http://www.savannahstate.edu/cost/eng-tech/faculty/jayjan2010/jay/hehslidec2.htmIt's just an example. But I want the pressure follow the rotation, so I can't use the gravity. What is gravity ? It's a force that attract each molecule with a same force. So I use a lot of springs, one spring for one ball. The balls are not like I drawn but like that:Each spring is attached from a green point to a ball. There is no friction between balls (theoretical).At bottom, there is no force if there is only balls (no other object) in the container. Here, I have a part of the sphere inside the container and I attract it with springs (like I attract the same volume of balls) like that there is no force at bottom, are you agree ?For resume: no force at up, no force at bottom but forces at left and at right
So imagine there is a friction like the friction of molecules of water not more, is it possible ? I want just a pressure like the molecules of water, it's possible because with gravity it's like that. If I said no friction, it's for simplify the study, you can add a small friction between balls, the balls will never move inside the container. But do you understand what I want to do with the container full of balls+springs ?I add what I called "top" and "bottom":
You can add friction between balls, it's not a problem, add the friction you want just add a little oil between balls ok ? Do you understand what I want to do with the container ?To put an image use this site: http://postimg.org/And take the link "URL forum"
I don't see the relation between your image and my device, could you explain more ?I'm agree oil wears off, there is friction, there is a lost by heating, I'm ok. But the energy of the device comes not from this. With the container there is a torque on the black arm that I resumed by the force F1. On the red arm there is no torque because the sphere put all the force on the ball link so the forces F3x and F3z can't give a torque. Could you ask me some questions about what you don't understand please, like that I can explain.
No, my device is not like the Cavendish experiment.There is only springs between the bottom (green points) and a ball and between the bottom (green points) and the sphere. Before to say if my device is in relation with yours I would like you understand what I try to explain:1/ Do you understand the container has no force at top, no force at bottom but forces at left and at right due to the pressure of balls ?
There is NO gravity !
Hey guy, before to understand my device with the gravity, try to understand without it. After, if you want your gravity add it, and you will understand the gravity change nothing. And it's possible to find a gravity = 0.001 in the Universe, no ? Ok, so first, try to understand what I want to do with the balls and the springs.
Do you understand my container with balls and springs ?
Sure, but the walls of the container have forces from pressure, ok ?
The container is not a rectangle parallelepiped. The container has walls except on the part where there is the sphere. The sphere closes the volume. The volume of balls is closed by the container and the sphere. The container has a part of forces from pressure. The sphere has the other part of forces from pressure, ok ?I want a torque (I resumed it with the force F1) on the container and don't on the sphere.
It's false, there is a torque on the container from the pressure of balls. It's logical.
There is net forces on the container:And these forces are not at the same value because the pressure increases more and more to the bottom, so there is a torque.
It's false, the pressure come from the springs not the air. Each spring attract a ball to the bottom (like gravity can do with a molecule of water).
There are movements: the arms turns at w.
I turn the arms before to apply the forces of springs (imagine the springs can be set ON/OFF when I want).
I'm not sure you understood the device
The first image is a cutting view and the second the top view. And if I want only one torque on the gyroscope I need to have 4 containers. 2 containers give a torque to the sphere only. I add stems (didn't draw) that can cancel forces on the from the surfaces of the containers:

Your balls and springs will not do anything but sit there. please provide a diagram of your spring layout.It's not easy to explain, and before draw a complex diagram try to understand the container can have a torque from the pressure of balls:1/ At top, you're agree that there is no force ?2/ At bottom, you're agree that there is no force because balls give forces from pressure and the springs cancel these forces, sure there is more surface at bottom than the volume of balls I attract so I attract the sphere too, and I attract the sphere to cancel all the force at bottom3/ At left there are the forces from pressure, I didn't draw all forces but only three, Fex1, Fex2, Fex3 and sure at right there are -Fex1, -Fex2, -Fex3 these forces cancel themselves but like there is the sphere there are more forces at left than at right. So there is a torque on the container, do you agree with that ?
