The Lee-Tseung Lead Out Theory

[Koen1]

I guess one of the cutting edge discoveries of Tseung must be
that he has invented a way to produce a constant force that is not constant,
yet still is constant. A pulse that is not a pulse.
Very inventive.

Dear Kul_ash,

Looks like we still cannot get to a common point to continue the discussion.

I have prepared the following diagram which is effectively an O-level Physics experiment.

Please look at the diagram carefully.  Do you agree with the angles and the scale readings shown?

Obviously, the direction of F can be different.  However, the experiment shows a possible outcome that obeys both Physics and Mathematics Rules.  Please comment on whether you agree with the diagram?

I would like to support both Kul_ash and Top Gun in their assumption of their force and movement path.  Both can be correct.

See the attached diagram.

We can first apply a pull (not the Lee-Tseung Pull) in any of the directions Z1, Z2 and Z3.  The bob will move away from the initial position A.  The Force applied does not need to be constant in magnitude or direction.  We can adjust until the final position is B and the final force is horizontal and equal to F.

The above paragraph is correct in Physics.  That means the radial path with a tangential force is possible as suggested by Kul_ash.  That also means using a horizontal force to pull the bob to the final position is also possible as suggested by Top Gun.

That experiment can be done in almost every high school or even at home.

The senario chosen by Top Gun is easy to analyze and clearly demonstrates that vertical work can be done by gravity through the string.  That work or energy enters into the pendulum system.

more golden egg claims...
still no proof.

getting boring Tseung...
...still too difficult to actually do some hands-on testing I bet?

@ Koen1:

Either Lawrence is a genius and we are all idiots or, the other way around.  I'm leaning toward the latter choice.
