AI Thread Summary

To calculate brake force for an eddy current brake, determining the frequency and characteristic length is crucial, specifically the skin depth and magnetic Reynolds number. The discussion includes shared equations and a model scheme to aid in the calculations. Participants are encouraged to refer to the linked thread for additional insights and references. Understanding these parameters is essential for accurate brake force calculations. The conversation focuses on the technical aspects of modeling eddy current brakes effectively.

TL;DR Summary: I try to calculate brake force for primitive eddy current brake, but I have problem with determining the frequency (skin depth) and characteristic length (magnetic Reynolds number)

Hello everyone, I try to calculate brake force for primitive eddy current brake, but I have problem with determining the frequency (skin depth) and characteristic length (magnetic Reynolds number). I attach the equations and a scheme of the model.

Thread 'Light speedup question'

If light travels in a wave, couldn't we "speed it up" by making it travel in a straight line?

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...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

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...
