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 'Gauss' law seems to imply instantaneous electric field'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
