The Lee-Tseung Lead Out Theory

[Top Gun]

Let me summarize our discussions on slide 3 or pendulum08.jpg.

(1)   The RHS represents 3 forces in equilibrium.  The theory to analyze them is the parallelogram of forces normally taught at high school physics.  Experiments based on this have been done many million times all over the World.

(2)   The pendulum bob moves from Position A to Position B as the final outcome.  In Physics and in Reality, this can be achieved in many ways.  The externally applied force can be horizontal, tangential or in any inclined direction.  This external force can be constant or can vary in magnitude.

(3)   The work done and energy imparted to the pendulum will depend on the exact force function and the path taken.  In the case of the pendulum, the path is an arc.

(4)   One possible scenario is to have no tension in the string as shown in Pendulum10.jpg. Another possible scenario is via an inclined plane type motion as suggested by utilitarian.  With these two scenarios, the potential energy gained by the bob comes totally from the externally supplied force.

(5)   With other scenario when there is tension in the string, we must do the entire force, displacement, work and energy analysis.  A possible improvement on Pendulum08.jpg is Pendulum14.jpg.  Pendulum14.jpg can be an actual experimental setup.  The experiment clearly shows that the work done by a small external constant force F is different from the gain in potential energy of the bob.

(6)   This means that we must consider tension in the string.  This tension has vertical and horizontal component.  There is horizontal and vertical displacement.  This means that there is vertical and horizontal work done by the tension of the string.  Or work done by gravity via the tension of the string.

                                                                          Brer Rabbit Meets a Tar Baby

- retold by  S. E. Schlosser

Well now, that rascal Brer Fox hated Brer Rabbit on account of he was always cutting capers and bossing everyone around. So Brer Fox decided to capture and kill Brer Rabbit if it was the last thing he ever did! He thought and he thought until he came up with a plan. He would make a tar baby! Brer Fox went and got some tar and he mixed it with some turpentine and he sculpted it into the figure of a cute little baby. Then he stuck a hat on the Tar Baby and sat her in the middle of the road.

Brer Fox hid himself in the bushes near the road and he waited and waited for Brer Rabbit to come along. At long last, he heard someone whistling and chuckling to himself, and he knew that Brer Rabbit was coming up over the hill. As he reached the top, Brer Rabbit spotted the cute little Tar Baby. Brer Rabbit was surprised. He stopped and stared at this strange creature. He had never seen anything like it before!

"Good Morning," said Brer Rabbit, doffing his hat. "Nice weather we're having."

The Tar Baby said nothing. Brer Fox laid low and grinned an evil grin.

Brer Rabbit tried again. "And how are you feeling this fine day?"

The Tar Baby, she said nothing. Brer Fox grinned an evil grin and lay low in the bushes.

Brer Rabbit frowned. This strange creature was not very polite. It was beginning to make him mad.

"Ahem!" said Brer Rabbit loudly, wondering if the Tar Baby were deaf. "I said 'HOW ARE YOU THIS MORNING?"

The Tar Baby said nothing. Brer Fox curled up into a ball to hide his laugher. His plan was working perfectly!

"Are you deaf or just rude?" demanded Brer Rabbit, losing his temper. "I can't stand folks that are stuck up! You take off that hat and say 'Howdy-do' or I'm going to give you such a lickin'!"

The Tar Baby just sat in the middle of the road looking as cute as a button and saying nothing at all. Brer Fox rolled over and over under the bushes, fit to bust because he didn't dare laugh out loud.

"I'll learn ya!" Brer Rabbit yelled. He took a swing at the cute little Tar Baby and his paw got stuck in the tar.

"Lemme go or I'll hit you again," shouted Brer Rabbit. The Tar Baby, she said nothing.

"Fine! Be that way," said Brer Rabbit, swinging at the Tar Baby with his free paw. Now both his paws were stuck in the tar, and Brer Fox danced with glee behind the bushes.

"I'm gonna kick the stuffin' out of you," Brer Rabbit said and pounced on the Tar Baby with both feet. They sank deep into the Tar Baby. Brer Rabbit was so furious he head-butted the cute little creature until he was completely covered with tar and unable to move.

Brer Fox leapt out of the bushes and strolled over to Brer Rabbit. "Well, well, what have we here?" he asked, grinning an evil grin.

Brer Rabbit gulped. He was stuck fast. He did some fast thinking while Brer Fox rolled about on the road, laughing himself sick over Brer Rabbit's dilemma.

"I've got you this time, Brer Rabbit," said Brer Fox, jumping up and shaking off the dust. "You've sassed me for the very last time. Now I wonder what I should do with you?"

Brer Rabbit's eyes got very large. "Oh please Brer Fox, whatever you do, please don't throw me into the briar patch."

"Maybe I should roast you over a fire and eat you," mused Brer Fox. "No, that's too much trouble. Maybe I'll hang you instead."

"Roast me! Hang me! Do whatever you please," said Brer Rabbit. "Only please, Brer Fox, please don't throw me into the briar patch."

"If I'm going to hang you, I'll need some string," said Brer Fox. "And I don't have any string handy. But the stream's not far away, so maybe I'll drown you instead."

"Drown me! Roast me! Hang me! Do whatever you please," said Brer Rabbit. "Only please, Brer Fox, please don't throw me into the briar patch."

"The briar patch, eh?" said Brer Fox. "What a wonderful idea! You'll be torn into little pieces!"

Grabbing up the tar-covered rabbit, Brer Fox swung him around and around and then flung him head over heels into the briar patch. Brer Rabbit let out such a scream as he fell that all of Brer Fox's fur stood straight up. Brer Rabbit fell into the briar bushes with a crash and a mighty thump. Then there was silence.

Brer Fox cocked one ear toward the briar patch, listening for whimpers of pain. But he heard nothing. Brer Fox cocked the other ear toward the briar patch, listening for Brer Rabbit's death rattle. He heard nothing.

Then Brer Fox heard someone calling his name. He turned around and looked up the hill. Brer Rabbit was sitting on a log combing the tar out of his fur with a wood chip and looking smug.

"I was bred and born in the briar patch, Brer Fox," he called. "Born and bred in the briar patch."

And Brer Rabbit skipped away as merry as a cricket while Brer Fox ground his teeth in rage and went home.

Let me give the more exact mathematical form using Integral Calculus.  The work done is obtained by the Integral of a Force Function F dot the infinitely small increment of the displacement ds.  This is shown in Pendulum13.jpg.

In Pendulum13.jpg, I further break the Integral into a horizontal and a vertical component.  This is mathematically correct even though this particular form might not be taught in standard classes at Universities.

The exact analysis should involve examining all the three forces separately.  There will be the additional concept of negative work.  Such a detailed analysis will satisfy the top professors at Tsinghua and MIT universities.

Have I confused the forum members more???

[Devil]

Top Gun, you are using this forum to display your mastery of Physics and Mathematics.  You have demonstrated conclusively that you do have extremely strong background on Integral Calculus.  However, you are doomed to fail in this open forum.

I watched your handling the discussion on slide 3 or Pendulum08.jpg.  That slide is the simple parallelogram of forces taught in every Physics Course.  People like Kul_ash had no problem with the slide but they realized that if they said yes to that slide, you are home free.  The following slides are just elaboration and extension of the same concept.  They just fooled around with you.  You fell for it.

As for the insults such as multiple personalities.  Tell them to go to Las Vegas.  There are many who dress like Elvis, sing like Elvis, dance like Elvis but are they Elvis???

In the virtul world of the Internet, multiple usernames in the same or different forums is the norm.  Tseung is stupid to reveal his true identity. 

Kul_ash is right ? you should not waste time on amateurs like him.  Approach the top academics in the West ? like MIT, Harvard, Princeton, Cambridge, Oxford, Paris, Tokyo Universities etc.  Write academic papers.

The experiment represented by Pendulum14.jpg alone is sufficient to point out the deficiency in blindly applying the Law of Conservation of Energy.  You have mathematically shown what the expected result should be.  Just do the experiment and show it to the top academics.  They can easily repeat and improve on it.  The outcome is never in doubt.

Top Gun was not the only one who fell for it.  I kept thinking why that it was so easy at Tsinghua and Shenzhen University seminars.  Now I know that many members in this forum can follow the physics and mathematics correctly.  But they just fooled around - having fun in my sratching my head trying to answer their "leading the wrong path" answers.

I just finished talking to Wang Shum Ho.  He said that he mentioned the name of Lee Cheung Kin and Tseung Chun Ning in his presentation at the Asia Economic Summit Conference when he introduced the New Energy Inventions.  China is introducing this gradually to the World.  USA is using the same strategy.  Visit their energyconversation.org website.

I can focus back on my fishing.  Did I tell the story of my spending 30 minutes to get a 12 pound fish last week with a thin fishing line???
