I G-force centrifuge mounted on opposite rotating platform

AI Thread Summary
A query was raised about whether a centrifuge creating a specific g-force, mounted on a counter-rotating platform, negates the g-force experienced by an occupant. The discussion highlights the need for clarity on the arrangement and motion of the centrifuge and platform, suggesting that a visual representation could aid understanding. Participants are uncertain about the dynamics involved, particularly how the rotation affects the perceived motion of the occupant from an external viewpoint. The conversation emphasizes the complexity of the scenario and the importance of accurately defining the system's parameters. Overall, the interaction seeks to clarify the physics behind the setup and its implications on g-force perception.

TL;DR Summary
Query - does a centrifuge spinning to create X g-force, mounted on a platform that is rotating the the same rpm's the opposite direction, negate the g-force? Or does the g-force stay the same but from an outside perspective the centrifuge appears stationary?

Welcome to PF.

What do you think the answer is and why? Do you know how to write the equation of motion of an object in the centrifuge as seen in a rest frame in the laboratory?

Also, can you show us a sketch or picture of the arrangement you are asking about? You can use the "Attach files" link below the Edit window to add PDF or JPEG images to your posts.
 
As @berkeman says, a drawing will help.

It sounds like you have two concentric cages, with the outer one rotating and the inner one not, Is that correct? If so, does that give you any ideas?
 
I have only one clarifying question for the OP:
From the vantage point of an observer outside the centrifuge contraption, how fast (if at all) is the occupant rotating?
 
I have no real clue what the OP is asking about lol, not the best statement that describes accurately the situation. The best I can make of it is that we have some object that is rotating around some point in a lab, say clockwise, and the whole lab is rotating (around the same point or different point?) in an opposite direction counterclockwise.
 
Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
