I find interesting the behavior of this apparathus ideated from myself.
The resultant of the forces on circumference of 2 liquids are perpendicular to the base. We have also a torque on the vertical wall.
If we fix the base to the center of a force of gravity,this should rotate,right?
This will be the end of it.
Greetings, Conrad
You have pointed the center in center of ball. This isn't what i ment. You have to fix the ball on the base. With a long tube reach the center of the earth. So this ball should rotate right cause momentums.

I do not understand what you mean. But it does not matter, because nobody can build a tube that reaches to the centre of the earth.
Never mind, Conrad
Should appen this

I know this is impossible to build,but it seems go counter 1law of thermodinamics,from my point of view
And than this rod thea reachs the center in the earth isn't a propblem. We can build a perfect circumference around earth and fix the ball to it. It should rotate anyway
Question of momentums
Cause rotation isn't causated by vertical forces but orizzontal,should roll
Gedankenexperimente are much too difficult for me.
Most of the things that can be built are already too difficult for me.
Sorry I disturbed your thoughts, Conrad
You didn't disturbed me affact. I like to confrontate with others. This is only a point of view
If it was possible to build this thing, it would not work. The "ball" is fixed into position relative to the center of gravity no matter where on earth the "ball" is located, so the "ball" will never see where its equilibrium is, and therefor finds no reason to start moving.

What appens to the torque?

There is no torque because you do not let the ball rotate relative to gravity.
The torque present in the ball is countertorqued by the string or rod that keeps the ball in position.
You could likely fix the ball upon a car with wheels. Will the car start to move if the ball is heavier in the front or rear? Most cars have approx 40/60 weight distribution on rear/front wheels. They do not automaticly start running for that reason. It is the same principle you're dealing with with your experiment.
It will not work. Sorry.

The forces causes the torque are not vertical,so not perpendicular to gravity. They are orizzontal. If i imagine a ball with 2 forces perpendicular to the center is obvious it don't rotate. But if these 2 forces are tangent to the center it should cause a rolling...

Hi Gabriele
The idea of overbalanced wheel is to use rather equal weights acting on opposite sides of fulcrum, than weights of different masses.
There is some interesting ideas based on Bhaskara's Wheel concept where fluid is used as weight.

Your 3D spherical concept with fluid is quite interesting.
All the best
If you note,the ball i drew roll (untill she reech equilibrium). I'm on the idea that if you place the fylcrum on the base,the same of the center of gravity,she will roll forever.
I'm on the idea that if you place this ball on the sea,she will move
