The graphic of |F||D|=1 is hyperbola or ellipse

AI Thread Summary
The discussion centers on the law of the lever in equilibrium, expressed as |F||D|=1, where F represents force and D represents distance from the lever's center. It explores the implications of different mathematical representations, such as |F|=|x-y| leading to a hyperbola and |F|=x-iy resulting in an ellipse or imaginary hyperbola, indicating repulsive and attractive interactions, respectively. The common version of the law includes contributions from the rest of the system, denoted as |F_r| and |D_r|. The author invites further exploration of these concepts on their website, specifically in the "Dynamics of the lever" section. Understanding these relationships is crucial for grasping the underlying mechanics of levers.

|F||D|=1 is the simplest form of the law of lever in equilibrium.
If |F|=|x-y| and |D|=x+y then |x^2-y^2|=1 is an real hyperbola.
In this case the interaction is repulsive.
If |F|=x-iy and |D|=x+iy then x^2+y^2=1 is an real ellipse or imaginary hyperbola.
In this case the interaction is attractive.

Perhaps it would help us understand what in the world you are talking about if you told us what F and D mean!
 
Yeah sure!

F is the force acting in D distance from the center of the lever.
The common version of the law of lever is:
|F||D|=|F_r||D_r|=1
here |F_r| is the sum of the forces from the rest of the system and
|D_r| is the sum of the distances from the rest of the system.

I have more on this on my page:

I think we've seen enough.
 
Thread 'Is there a white hole inside every black hole?'

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...
