The Lee-Tseung Lead Out Theory

[Pirate88179]

Lawrence:

I think I follow you and agree to a point.  In your system of the suspended pendulum, I understand and agree with the equalibrium of the three balanced forces at a given point.  You mentioned the initial "push" as being controlled by the experimenter, and that the pulses could be timed in such a way as to produce resonance, which I also agree with.  The example posted earlier about the child in a swing and a small force (push) timed and repeated correctly can send the child in the swing to great heights and velocity.  But, what I was taught, and possible inncorrectly, was that if you added up all of the energy used in the pushes or pulses, they would equal out to exactly the kinetic and potential energy conveyed by the swinging child.  Of course, this example does not involve magnets or magnetic fields.

So, my question is, given that the correctly timed pulses are an efficient way of propelling the child to great swinging arcs, but, they none the less represent no more than the total energy in the system, where or how does any additional energy come into the picture?  I appreciate your patience in your explanations.

I don't know physics. I think physics should get to know me.

Personally I try to imagine how far I can throw a person up into the sky with a gentle push. A gentle push seems to be enough to throw a person up by say 0 cm? Correct me if I'm wrong but it appears not enough to even lift the passenger off the ground let alone launch them by means of gentle push.

The fact the swing was already moving isn't so much of an issue.

the part where a small push is enough to lift 80 kg of meat by 30 cm really makes no sense with the established theory. One of the 2 has to be wrong.  If I give you 2 blocks 1000 kg, block 1 is attached to 50 meters of wire, you will be able to swing block 1 up against gravity.  Block 2 remains in it's spot, you cant even lift it - what are we talking about here? LOL!

look? http://www.youtube.com/watch?v=r5ok4pPgVYA hahaha??

wait, this is pretty convincing... http://www.youtube.com/watch?v=BDla-x-l4Hc no?

I think A standing wave is still a wave?

if 10 Joule is the energy required to lift a kg by 1 meter(is it?). Then we need about 5 Joule worth of pulses. It appears you can get about twice the height out of it.

I think it's interesting how the bob is already decelerating. If 9.8 m/s is the maximum acceleration then that must also be the maximum deceleration? (I'm guessing here)  As the bob is already decelerating while moving upwards could it be that gravity has some modified influence? You may test what I mean by pushing an object towards the ground faster as it would drop. You feel you are not assisting gravity but replacing it.

If you toss an object in the air it kind of floats there for a moment then reverses direction. It doesn't just reverse direction but it waits for a bit, this is the moment the pulse disturbs the system most efficiently. Push the swing the moment right after it reverses direction.

It's like nature shifts the gears from decelerate to accelerate and you have a small window of free motion while the sprockets are detached.

Dear Bill,

I was taught incorrectly as well.  However, I had my lesson in a painful way.  When I was still a naughty boy (almost half a century ago), I pushed the punch bag a few times and then stood there for it to knock me down.  The punch bag was a few hundred kilograms.  The force knocked me a few meters away and down.

I was convinced that my couple of pushes could not have provided the force or the energy to give me so much pain.  However, my physics teacher told me the same thing as your teacher (The sum of energy of the few pushes added together was the culprit.)

It took me 50 years later to realize that I was taught the wrong thing.  (Thanks to Lee waking me up at 7:30 am from the hotel.)  I actually Lead Out some gravitational energy in each of the pushes.  The culprit was the sum of my energy and the Lead Out gravitational energy!

If I did not believe in my physics teacher, the Lee-Tseung theory would have been out over half a century ago!

Believing the teacher blindly Leads Out wrong results even though the Pulses provided the painful lesson.

The established theory is called mechanical advantage.  You are not lifting the 30kg straight up, but at an incline, and it is therefore easier to do, but the total amount of energy needed is the same, assuming no friction or air resistance.

If what you are saying is true, creating an overunity device is trivial.  Just have the pendulum hit something capable of converting the kinetic energy to electrical, and use that stored charge to "pulse" the pendulum when it is on the downswing.

Lawrence:

So, then might it be possible to contruct a decent size pedulum where the "weight" would be a cylinder shaped magnet and suspend it from two lines into one such that it would keep it from twisting, and have it pass twice during it's period through a coil, or a series of coils, to generate enough power to run a small occilator that would add enough of a pulse at the correct time to maintain the pendulum motion?  This would be fairly easy to construct on a smaller scale for testing.  Do you think this would be possible?  thanks.
