Of course there are. Point being, in Shipov device for example
clearly there is acceleration to one side but then he allows
masses to go beyond 180° and of course it curbs itself.
If he curbed the masses at the axis before they crossed
180° there would be no back reaction.

nix85:


Thank you for considering my experiment, but the arrow in your drawing is backwards.  As the hinge opens, the pivot moves upwards. Then, the instant the hinge stops, the pivot moves back downwards an equal amount. Due to Conservation of Momentum, the mechanism itself will move however it has to for the masses to move in a straight line, rather than in a curved path. (In the absence of torque input).


So what will happen if the operation is motorized?


And, of course, there are other ways to use a hinge.

I was not referring to you but another guy who built my design, of which
i posted a photo few pages back, and my design is quite different from yours.

Springs can be utilized but it is advisable to avoid them cause they are not
needed.

There are better ways.

The text below is a copy of our post of May 17, 2021, 03:38:48 PM.   
----------------------------------------
1) 0.1 kg.m/s = 0.1 kg.m/s. The last equality shows the validity of the law of conservation of linear momentum in this particular case.
2) 0.005 J > 0.002 J. The last inequality shows the invalidity of the law of conservation of mechanical energy in this particular case.
3) Modern (and even not so modern) technologies allow reducing of friction to a certain value/limit, beyond which the experimental error (due to friction) becomes negligible (less than 1 %).
----------------------------------------
Looking forward to your comments.

One question, if possible.
Until now your posts describe rotational systems, consisting of solid bodies and liquids. What would happen if we use gases (air for example) or dust, which rotate in some manner? Curious to know.
Looking forward to your answer.

Please have a look again at the link https://www.youtube.com/watch?v=xX14NK8GrDY&ab_channel=PeterAxe and at the related comments section. In this comments section an egghead-wiseacre, whose pseudonim is Dark Light 2.1, does his/her best to reject obvious truths. This person Dark Light 2.1 is a real clown! Please follow this discussion, if you like.

It depends on what you ate, bean gas gives best centrifugal pull.

You wrote: "Two of the devices in my recent pictures worked as expected." Would you be so polite to remind me in which of your posts these two devices were described? (Because your dialogue with nix85 (as well as with other colleagues) here bombed me with a lot of information (this is not a reproach!) and I forgot in which of your posts these two devices were descrbed. I am sorry for this.)

1) Please have a look at the two links below:
https://www.youtube.com/watch?v=xX14NK8GrDY
https://www.youtube.com/watch?v=zPqEEZa2Gis&ab_channel=IthacaCollegePhysicsIthacaCollegePhysics
2) The second link suggests another possible method (among many others) for reducing of friction (inside the zigzag channels in the first link above) practically to zero. The key component of this method is liquid nitrogen. The latter however proved to be extremely cheap -- only $ 2.00 per liter.

Looking forward to your comments.

As for reducing friction, electropolished stainless steel
+ low viscosity grease is the best.

It is not just back torque. He said device jumped in the air then back down.

Back torque can just lift one side and sink the other, NOT propel whole device up.

But this configuration is no good for reason already illustrated. Two points connected
by a spring will clash in straight line pushing the pivot down.

There is a workaround, using springs in different way.
Key being that springs here act purely in horizontal way.

Again, this is just for demonstration of the basic principle
which can be demonstrated without springs as well acting
on the axis.

This is of course not a solution for actual propulsion system.
There are better solutions, i already shared water one,
you did not recognize it. There is an even better one,
not mine idea, i am not sharing that one.
