Roll on the 20th June

I accept your apology. I wouldn't expect you to apologize for having a different view point. If we all shared my perspective, I wouldn't have joined the site. By all means, oppose me! Challenge me!





ATTENTION ALL. If you are in contact with any physics professors in Australia near Boronia, please contact Archer Quinn (The Eskimo Quinn) as soon as possible. He has offered to allow his device to be tested before Tuesday, 10 June 2008. This is a very important offer and would bring to rest much debate.

My money says that someone was hiding behind that wall to lif the large weight on the first half of the motion, then when let go the light weight was lifted gracefully back into Archer's hand. Though I may not have all the details, Id love to hear the Archurian analysis!

A couple of things:

1. We've lowered the tone..please keep it this way.

2. I am looking at the H.264 version of this video (video 4) and I'm not seeing this, PP.

In fact, he swings the camera around fast enough that you can see the other end quite clearly as the bottle end is still going down; it is about one second of time.

So while there may be some trickery, I don't think THAT is the trickery we're looking for.

Hi All
First I have to be honest here I hope the other videos are better because I didn't see anything there, I didn't see the 20L on the other end and I'm wondering why it bounced back up when theres no downward force on the other end is there a spring in the middle (...)

(emphasis mine)

You're getting it, slowly.. keep thinking about it. Think 'balance beam'..

I thought he said 20kg, not 20L...........

3rd EDIT: Damn, he did say 20L.

But anyway, the weight bounces because the energy gathered in descent rebounds.

Did the idea of inertia go south recently?

The beam is OVER-balanced on the light end.

Let's start with equilibrium.

The concept of a 20:1 lever means that it will balance with 20kg on one side, and 1kg on the other.

IF I apply .2kg of force downwards to the 1kg end it will travel downwards, and then up, and keep  oscillating between going up and down until all the energy imparted by the .2kg of force is used up by movement to defy gravity and friction and stops at balance. Depending on the range of movement on the 1kg end, it will gather energy due to it's attraction to gravity until it hits the "ground" and rebounds.

At the time that it "hits" the ground, the heavy end is still traveling upwards with the energy, with at least the same energy the light end gathered on it's descent.

It creates "slack" in the twine used on the light end attaching it to the beam. When the heavy end succumbs to gravity and starts traveling downward there is no countering weight for the length of that "slack" and the energy of 20kg traveling with no counterweight is imparted to the 1 kg side, "jerking" it upwards.

When the slack area is now taut we are back to our balanced beam and it's tendency to oscillate up/down towards equilibrium, but also using the energy left over from the "jerk" to lift the light end from the ground.

This is why the light end "bounces" back up.

EDIT : Had to take out extraneous words at the end that i didn't form into a coherent sentence.

2nd EDIT: a few directional specifications  added for enhanced clarity.

The logic is quite simple.. note a couple of key points of the machine:

1) When totally unloaded, the long (input) end rests at ground level - it's heavier on this side. *This is important*

2) When the workload is applied to the short end, the long end rises.. no surprise there.

3) However - when the input weight is applied to the long end, the lever balances, with the workload at roughly half height. This is the ground state of this machine - in balance, with the load already half-way lifted. When perturbed, the machine will always settle back to this state.

Since the ground state is at half-lift, the 20Kg weight only has to be lifted the remaining half distance to the top - it only needs to do half the work that it would, were the ground state actually at ground level.

With a 5:1 lever, a 2Kg weight falling 5m can raise a 10Kg weight by 1m.

Or - it can raise a 20Kg weight by half a meter - and that's exactly what we're seeing. You don't need 10:1 advantage to perform a 5:1 operation.

Also, you will notice that when he's placing the weight on the long end, he actually has to do work to raise it to full height.. again, recall that the beam is heavier on this end.. so how much weight is falling, again?

Kai, what we're seeing is a lever - nothing more, nothing less. Do you see anything other than a long beam pivoting on an elevated fulcrum - anything that differentiates it from a teeter-totter, in basic concept? Where is the novel mechanism that supposedly makes this lever behave differently from any other lever?

Egyptian Fulcrum my arse, this is a total joke.

Good points of observatioin gentlemen. Interestingly, when I watch the videos, this guy doesn't actually sound insane. I guess first impressions can be misleading.  I think we would agree however, that a true experiment or verification would START with an unloaded beam demonstrating that it could maintain a balance on its own. This part of the demonstration was left out and would have helped to eliminate the effect of any imbalance in the lever from skewing the results. As well a tape measure would have been a good idea to demonstrate the mechanical advantage well.

But instead, we see that at rest, with no weights attached, the long end (heavier) sits on the ground! That is just fucking hilarious! Can a guy who can operate a video camera be so stupid as to miss this? NO... he's not that stupid. Archer is a liar and a charlatan. This folks, is a deliberate hoax and a very desperate one at that.

@Archer

Thank you for your video but i don?t understand what happened.. why you did something so big and hard to show ?
Please request somebody to hold your camera while you show or use one tripod.

Thank you
