Variable counterweighted pendulum...

[iacob alex]

.....I suggest,can be a short clear definition of a possible gravity motor.

     Somehow and sometime,the art and the science are on the same "path"...

     You can have a moment of new thoughts ,if you take a look at:

     www.youtube.com/watch?v=mVRgY88ecIs

     So,you can easy think and build/test ,step by step;

         -a pendulum
         -a counterweighted pendulum
         -a variable counterweighted pendulum

      The problem of "variability" is so large,but the main purpose is to get a self-moving scheme,due to gravity.

.....as a simple expression (and suggestion to build a self-running mechanism!),you can watch at:

    You need to play gravity fall and inertia storage,nothing more...

I like it alex. Just replace the guy with a weight that moves itself around the circle and extract the power at the axis. Doesn't seem to complicated.

Interesting.  Replace the guy with a heavy gyroscope, that can maintain its orientation relative to gravity, head to the sky.

         Hi !
   
    So,we have a simplified arrangement,with a single variable arm/spoke.

    You can see it as a particular see-saw game,with only one active "partner":not just swinging (translating to and fro on the arm/spoke),but rotating 360* in the same time.

    I agree with you: "just replace the guy,with a weight that moves itself....".

    How moves this weight?!

    It can move in so many ways...

    Let's recall and use an ancient design.

    Something  simple ,as a "door hinge" 180* rotation ,that so old Middle Ages  proposal can help us to think about the variable arm:half-turn,beginning with the bottom position, is hanging as a small arm,in the top position moves (if "helped" by inertia) as a great arm for the next half-rotation.

    The basic idea is to get an endless rotating body,due to an unbalance of couples:a torque difference on the same side of the fulcrum.

    A greater size means a greater fall (...and inertial storage...),so we can easier "pump the starting unbalance" ("tumbling" hinge )for the next full/360* rotation...or beginning with a certain threshold of size,we can hope to achieve the self rotation  ,due to a simple game between gravity and inertia.

      All the best! / Alex
