    Couple Moment
AI Thread Summary
When a couple acts on an object, it induces rotation without causing translation. The rotation typically occurs around the center of mass, but the discussion raises questions about rotation points when the axis does not align with the center of gravity. Couples generate equal moment arms, which can lead to complex rotational dynamics if the axis of rotation is offset. Understanding these principles is crucial for analyzing the behavior of objects under the influence of couples. The implications of this knowledge are significant in fields such as physics and engineering.

when a couple acts on an object it will tend to rotate it and it will not tend to translate it

But the sentence "tend to rotate" but tend to rotate about which point or axis?

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...
