PM fancy pattern...
« on: November 19, 2009, 11:14:34 PM »

    .....or a simple way,so to develop this old "dream",can be expressed based on theory,as a "gravity unstable equilibrium".

        The state of unstable equilibrium,can be your pencil,standing on its tip (inverted pendulum) on the table.

        Whereas a normal pendulum is stable,when hanging down,an inverted pendulum is inherently unstable.

        A  simple game,in the line of stability,with an inverted pendulum (cart with a pole) ,made possible the development of robotics.

        A simple game,in the line of unstability,with an inverted pendulum equivalent (lever with an hinged arm ) can open an unusual way-out for PM?!

        Even more: inverted pendulum games,can be a common starting point for next steps /energy and transport !?

            All the best! / Alex

  ....as a simple game with gravity,you can see and "exercise",if you take a look at :   http://www.backshop.co.za/products/inver_table.htm
 
      Really,it's a special "see-saw" ,that plays the gravity unstable equilibrium,via an inverted pendulum "equivalent"...so that you can swing,but more interesting,you can rotate continuously,also

         All the best! / Alex

  .....playing the idea of "gravity unstable equilibrium",can develop a torque/moment arrangement.

       Moments can be viewed as a rotational natural action/flow.

       Moments cause a body to rotate,or change angle.

       Moments can arise when gravity action do not act through the center of gravity (equilibrium) of a body.

       A moment is created by the offset between the support and the center of mass.

       In a body-tail configuration(fish,bird),the tail/empennage plays an important role in the dynamics (unstability of the body vis-a-vis medium).

       Because the basic medium is the inertial property of space,we must take into account not only the gravity fall/flow...
