.....as an elementary arrangement (see Milkovic's double oscillatory system),plays swinging motion of a pendulum hanging in a mobile fulcrum.

The reference line of this compound motion is a horizontal one,of the fixed fulcrum,and plays smalll gravity potential differences.

How about a vertical reference line ,so to play greater gravity potential differences?

Hi Murilo!

Bessler's pendulum is a "common" clockmaster's one (that of Huygens),playing small swinging ("linearty"),around a bottom point.

Milkovic's pumping system (oscillating head/"hammer" due to a swinging pendulum ) plays alike the very old oriental shadouf...again 'linearity".

Now:how about an inverted pendulum(a "classical" robotics case...),free to fall 180*(top-down),playing "nonlinearity" (v*v ) this time....?!

I have played around with Milkovic's double oscillatory system a great deal and I came to the conclusion early on that it, like every other configuration I have experimented with, eventually requires some manner of external impetus, a pulsing of the pendulum and regardless of what orientation you might arrange it, it will run down and require an external energy source to continue its motion.

The question is, what form of external energy do you envision using?

What if the pendulum was made really big and a high gear ratio is attached to the center so that the lever lifts really high but the pendulum doesn't fall much and thereby doesn't effect its oscillations as much...

.....of a possible gravity power collector,vis-a-vis a wind power collector counterpart,refers,in my opinion to his extreme simplicity (this time we have in view a two-arms one,let's say a Savonius type or a standard meteo one).

One variable pair (concave-convex shape,constant arm) of a wind power collector ,can suggest for a gravity power collector something alike:any shape (the only point is CoG),but with a variable arm.

It's a kind of "gravity cranking",a leverage that converts rhythmically a fall (PE into KE)into a rotating movement...as we pump "a flow of PE" into a "turbine effect",turned by this discharge...

For example, I mean 2 strategically opposite and auxiliary pendulum JUST enough to 'trigger' and 'un trigger' individually the main active hammers... almost as an active chronometer.

Not necessary to say which and where hammers, I hope!

Johnatan,
don't be upset... mistakes in names are not intentional! OK?

On the left side the rim of the wheel could act like a ratchet where when the lever lifts up some it applies not force but when it crashes down it applies some force to the rim of the wheel. On the top there are pegs on the end of the wheel that catch the pendulum and pulls it a little when it is higher up. The pendulum will fall when its swing is to the right and the pendulum will rise when its swing is to the left just like that website but the website is without the wheel resetting it.

preocc,
yes this may be an application for auxiliary pendulum in a wheel.
You're smart.

In the thread 'origin of gravitation' there is a known example of a mag wheel, where a set is also used to jump and arrange the mag sequence to external mag.

With 'g' the application of 2 pends. is very similar, p.ex., at 12h and 6h.

cool- who else thinks I'm smart?

Thank you murilo.

Who on the forum has the skills to calculate whether this would be a good idea? If someone could pull some numbers out of their angle side side that would be a appreciated. =-D

Milkovic's pendulum is reset when someone pushes it, just like any seesaw.
Your animation doesn't show the forces in proportion, or the vectors that they obey.
The pendulum, once it has used its initial energy given to it to push, or pull, the wheel partway around, won't reset like your animation shows, because the wheel would have to lift the weight of the pendulum back to the position it was in when it was first released.
If you set it up so the arms were the same relative lengths as milkovic's, you'd get a similar performance, but it would still need a push, just like any pendulum or seesaw, or it would stop.

I see in the animation that when the pendulum is moving to the right it is caught by a faster moving fly wheel and moves with the fly wheel some. This should increase the distance to the right that the pendulum climbs greater than if it were freely flying.

Milkovic believes there is a lot more force on the seesaw than is requird to push the pendulum. If that's true then maybe more force is applied to the fly wheel than is required to push the pendulum...

wouldn't it be pretty funny if we were looking at half of Bessler's wheel because he had a pendulum on the outside of it if it were the same as the animation I showed? We all think we can't see the inner workings of the wheel but what if that pendulum on the outside is the secret?

[iacob alex]

.....as a practical device,is a very old one in the history of mechanics:the shadouf ....3000-4000 years ago.

Regarding theory...it seems to be a new one:a certain kind of oscillatory motion of the "head"/lever,due to a pendular swinging of the "tail"/lever.

It can be considered,in my opinion, as a first step in the huge domain of the future "öscillatory"mechanics...

Boys,
up to now I saw no one draws about that triangle pendulum.

I guess that those heavy 3 weights triangle may give a better result than one single bar type...

Still guessing, with 3 distributed weights they must be different than that with weight equivalent single weight...

At least a momentum and time compensation will happen.
