Centrifugal "key"...

[iacob alex]

.....to play ( "awake"...) a dynamic relation with inertia , at :
https://youtu.be/hlZ0k5OYpEo
We can see the first step ( rotational vector ) , the second ( two ways/to and fro translational vector) and...a possible third one ( one way translational/ tractive vector...) ...if we keep in mind the Viviani curvature of the double rotating eccentered mass ( di Bella mechanism /1967) and a certain arrangement of a quadruple connected parts.
Have we an unique answer, solution for a paired problem ( energy and transport ) !?

It's on the right lines but it's not there yet.

You need the four derivatives of motion for an energy cycle analogous to the Carnot.

Hi Senax,
I think the Carnot process is not bad example.

I think this one is better: the Atkinson cycle

https://en.wikipedia.org/wiki/Atkinson_cycle

a very good example is here

I tried to copy the gif to the attachment, but the file size was to big.

...

I refer to the Carnot for its theoretical properties. I'm not concerned with
practical considerations.

Carnot Cycle. The most efficient heat engine cycle is the Carnot cycle, consisting of two isothermal processes and two adiabatic processes. The Carnot cycle can be thought of as the most efficient heat engine cycle allowed by physical laws.

Hi iacob alex

I think in the real world this demo is a lot more complex.

For example the rotation speed will vary over the rotation cycle.

Hi Senax,

the Intention to pass the link to you

https://en.wikipedia.org/wiki/File:Atki ... Engine.gif

is the moving process, not the Carnot process.

you can see the pistons as a pendulum mass, a double Pendulum.

Turn the gif by 180 degrees and it will be top heavy.

The mechanical process way in the Wheel is part of

The physical world of action is due to acceleration (Newton...) , we can get from rotational inertia so easy ( remind the Lab Centrifuges...or ultracentrifuges https://en.m.wikipedia.org/wiki/Centrifuge ).

Only centrifugal force is not the solution,
You must break the circle, change the path of the moving mass.

You can turn the eccentric weights with 50 rps and you will not see any side effect.

The rotation causes everything to flip at 180 degrees with respect to gravity
and Kerry Waenga uses a spring to store potential energy so that it can be released at any wheel position. I suggest you go look at that discussion.

My single setup of 1 mechanism gave me 48 degrees of extra rotation
beyond the 72 degrees required for each of 5 mechanisms.

very hopeful.

You are just making your wheel heavier. Stop now and think about it before you spend to much time on it.

If i have a mechanism that can rotate one degree does that mean i only need 360 mechanisms for my wheel to work.

[nebollinger]

I took a look at Kerry's drawing again and noticed that the radius of the
weights is not all the same and thus the balance of the wheel would be affected by that depending on how you made it. I scratched my head and finally made a mockup to see where the balance would be and sure enough it matched Kerry's drawing.

You can see my crude ptototype in the attached photo that shows what I
discovered.

This hub design demonstrates that 3 washers on right ....
with a shorter radius and 2 on the left with a longer radius
are balanced and the wheel does not rotate.
The arm at 6 o'clock is not real clear to see the arc
but it has a short radius like the others on the right.
The 2 arms on the left are straight out from the axle
but the ones on the right are angled to the right and make
the radius shorter.
So if the wheel is balanced then its not "off balance" that makes
it run?

Sorry the photo came out 90 degrees to the left. rotate it to the
right 90 degrees.
