Who is .....

[Unbalanced]

Thank you John,

Have you any idea who created the plaque?

[path_finder]

this object has been created by Siegfried Kretschmer, at this time a famous sculptor, having perhaps some undisclosed and unpublished data

[Unbalanced]

Thanks a lot Path_Finder, It is hard playing catch up sometimes. I'll digest what has already been discussed.

Thanks again, Curtis

Dear Unbalanced,
May be the engraver was not a technician, and like Villard de Hennecourt was not careful enough in his drawing.
The teeth on the keystone do have a squared shape (which obviously is never used).
IMHO the shape of the teeth could be in the reality almost polygonal, like here:

wich is much more in accordance with my personal belief, and especially much more easy to build at the time of Bessler.

Just returned from looking up Antikythera mechanism. I had looked at that before.

A trip to Germany come summer may be just what I need. Fascinating stuff.

I really appreciate all the links.

Good Day Grimer,

My name is Curtis Ciszek aka Unbalanced of Bend, OR. I was the "brave chap" that posted about using the z-axis.

I am working on a build to this end and so wish to reserve further comment until I have had the opportunity to experiment.

I've not had an opportunity to comment on your posts earlier so I am doing it now. I have very briefly skimmed through them and I like what I see.

I have taken the liberty of slightly editing your excellent point about the wind generators.

Wind turbines utilize three blades for a very good reason. The rotating blades act like a gyroscope. As it follows the changing wind direction and pivots about a vertical axis, gyroscopic precession tries to twist the turbine into a forward or backward somersault as illustrated by the Eric Laithwaite video, specifically 2-minutes in, to 3-minutes in

http://www.youtube.com/watch?v=kRCq3wLMfIM

For each blade on a wind generator’s turbine, precessive force is at a minimum when the blade is horizontal and at a maximum when the blade is vertical. This cyclic twisting can quickly fatigue and crack the blade roots, hub and axle of the turbines. By using three blades only one blade is ever in the vertical at any given time.

Specific examples like this are a big help for people put off by a more abstract mathematical approach to get a feeling for what is going on. That example certainly helped me.

[Unbalanced]

Grimer,

I am glad to be of the least help. This 'somersault' that the blades or flywheel are want to do, only occurs when the base is swiveled, i.e. when the turbine of the windmill is being rotated to face the wind as Eric's unique gyro did when he set it free to precess. The precessive force that creates this "canting" or leaning over and the subsequent auto-rotation of the base is seemingly quite a strong and instantaneous force.

I have searched for a method to measure this force on line and have come up empty handed except for this possibility. It would be easy (though time consuming) to replicate Eric Laithwaite's gyro. By measuring the bend or deflection of one of his spring steel arms when bent from the vertical, at a stand still, with a spring loaded fish scale. This would give a fairly good indication of the amount of ft-lbs required to deflect these springs as much as they are shown to be deflected while his gyro is allowed to precess freely. Does the CF that is trying to keep these spring arms upright also need to be calculated? I believe so. Precession in Eric's video is fighting CF and the spring tension to deflect as far as it does.

The most incredible aspect of this demo is not shown and that is when his gyro slows further, the precessional force, hence velocity, increases until the RPM of the flywheel slows to the point where precession breaks down and disappears. As this happens the gyro goes from a steady cant to wobbling at its greatest degree.

If we increase the spring arm diameter (tension) and increase the quantity
of mass per arm, we can decrease the RPMs necessary to achieve the same results.

On this note, by doubling a gyros diameter we are able to half its rotational velocity to achieve the same gyroscopic and precessional forces. Bessler doubled the diameter of his wheel and halved the RPM another coincidence? I doubt it. The more I research these precessional / gyroscopic principals the more I am convinced that Bessler was utilizing these forces.

All forces directly associated with rotation as is the Coriolis effect which may also be thrown into this PM device in one rotational direction.

I may be wrong on this but I believe Bessler's wheel worked better in one direction than the other. I suspect all of his lifting demonstrations were conducted with a CW rotation facing the wheel on the side where the force was applied, i.e. facing the wheel as in his illustrations at Merseberg and Kassel etc.

This may be nonsense as the Coriolis effect favors a CCW rotaion in the northern hemesphere.

[Unbalanced]

Dang! double post again

[Grimer]

As far as the Coriolis effect is concerned I'm sure that at the scale of Bessler's wheel it is far too tiny to be significant.

I'm reminded of the African gentleman who wow's tourists on the equator by having a bucket with a hole in it. He demonstrate that on the north side of the equator the water rotates one way and a few hundred yards on the south side it rotates the other.

There's plenty of web stuff on the scale effect of Coriolis if you're interested

Quite so. We are talking about Jerk,d³x/dt³, the third derivative of position with respect to time. I discussed it here:
http://www.besslerwheel.com/forum/viewt ... 1729#81729

Force is to acceleration as Third Order Action is to jerk. Unfortunately we need a new name for this D'Alembert action since jerk, as defined, is the equivalent of acceleration, one order removed.

Let's call this action Persuasion since it's pretty obvious is you look at Eric's demo long enough that we are dealing with a servo-mechanism -

And Persuasion is better than Force as Aesop recognised all those years ago.

We are getting there, slowly. There is one more level to go however which I hope to explain in a future post.

[Unbalanced]

Since I have already given away the baby and the bath water and reconciled it with myself, I will post my revised mechanism for the conversion of precessive force into mass shifting leverage to maintain OOB.

This particular lever system is what I call Bessler's 1x4 or 4oz lifts 1lb. My doctor of physics buddy tells me that this lever configuration is an anomaly and my experiments testify that it is lightening fast, makes the stork bills seem slow, cumbersome and wrought with friction.

I would like to credit Winkle for his insight and sharing and Fletcher for bringing these particular MTs and Winkle's insights to my attention.

Curtis .. could be plz explain how it is supposed to work in detail ?

N.B. Storksbills can be replace with pneumatics or dual radius pulleys & rope, or light chain & sprockets for example.

[Unbalanced]

There is a potential fault in this design that I have detected but it is a simple mechanical fix.

In short form:

As weights "C" are deflected off of their plane of rotation by precessional force, top and bottom wobble. the linkage "D" spreads the rails near the rim (as detailed on either side, bottom) which throws the weights "A" toward the axis of rotation (the center.) CF returns the weights "A" toward the rim in turn aided by the opposing weight "A" whose rails are spread at the bottom.

Weights "C" are deflected off the plane of rotation progressively from 3:00 to 12:00 and in the opposite direction from 9:00 to 6:00 CCW by increasing and declining degrees respectively. Weights "C" are in alignment with the plane of rotation at the 3 and 9, the equator. This is an observable phenomena.

Weights "A" are suspended on grooved wheels (shown but not labeled) think pulley or turning block wheels such that as the bars are spread the weights are levered inward toward the axis.

As long as I am on the subject and giving away my A-list material, these rods or levers could easily run the full diameter of the wheel leaving no weight on the ascending side ala MT 66, 68, 69 levers.

I knew who gave me this today and I know how seemingly ridiculous this sounds but it happened at 2:30 PM PST today and I am still so overwhelmed by this experience that I have lost my appetite and ability to concentrate on anything else. MT66 levers, no inside axle, weighted arm tips spread rods projecting weights on rollers riding on the rods.

I have started a build on the latter and probably won't sleep until it is finished.

The image below is the vision I had this afternoon. The quantities of the masses are unimportant to the extent that they would do well to all be equal though I believe this will work as shown and can be enhanced in a number of ways.

I feel as though this one should be posted under JC's thread Circumstances in which Gravity alone can turn a wheel or whatever its called.

The image below is pure Bessler it came in a vision and I deserve the castigation such an outlandish statement invites. Truly I am no medium and I have never been known as one to have fits of fancy or a channeler of the dead but this came as I was driving and it was so real and vivid that I had to pull over and hyperventilate and couldn't stop laughing for an hour.

Now I thoroughly expect to hear this has been tried a hundred thousand times to no avail but hey! as far as I'm concerned its not mine to hoard.

I had a toy as a kid that worked on this same principle and it is used as a tensioner of backstays on sailboats and it is an unusually powerful shifting configuration.

[Grimer]

How funny. One of my grandsons, George, had something similar in his Christmas stocking. You attach one end to the top of the fridge, tension the strings, pull them apart and the "man" climbs up the fridge door.

No need for wheels in his case since the plastic "man" has a low coefficient of friction.
