Milkovic's Pendulum

[James_Arne]

P.s., I have solved his feed back loop system and sent it to his son Jovan.
A 1kg weight 30 cm's from axis will have 70% less force than a counter weight suspended from the same axis.
to easy once it is diagrammed. And with a double oscillation ? 50% of the extra force can be utilized for work. And this is on each stroke.

Like this ?

Just in case it works you'd maybe better build the thing ?

Will see what I can do. All I have to work with is some thin plywood.

With what Furcurequs has mentioned about prototype building,
working with inexpensive materials can work just as well as
anything else.
What I might do is show how a pendulum of this type can be built with only a saw, a drill and 2 clamps.

With a simple design like this one previously posted, this wheel (link) shows how quickly 100% over balance can rotate something.
With 30%, not sure why this pendulum concept wouldn't work. The catch and release mechanism would need to be efficient but that shouldn't be to diffciult to do.
The c&m mechs would hold the weight on the pendulum and as it is lifted, the weight could be pulled free allowing it once again to swing from the pendulum.
And if it's of comparable size, should be able to do a fair amount of work. After all, it would be working continuously. Still, it wouldn't be perpetual because perpetual motion is impossible.

The link you posted showed very little. You can get some degrees of rotation with overbalance, but no where near the amount needed per mechanism, in this case, you need >90 degrees, with 8 you would need > 45 degrees.

Pendulums offer a much more dynamic mechanism, with a greater range of forces. Moving the pendulum axis increases or decreases movement, depending on timing. I guess you will just have to build to see what problems you face.

This morning I messed around a little bit with a dowel where I hung a weight from each end.
to have something like this rock back and forth might not be that difficult.
I have thought a little bit about a wheel and may try it just to see what happens. kind of doubtful it will work but ...

edited to add; did a quick diagram. think a snowball in a certain hot place would have a better chance.
