Stabile pendulum vs. Mobile pendulum...
« on: August 27, 2009, 06:31:47 AM »

  ...if we use the terms of Alexander Calder's  Dynamic Sculpture (see "Performing Seal"-1950),can be simply a setting side by side of a common pendulum(pivot-rod-bob) with a Milkovic's pendulum-lever system.

    A common pendulum (with a fixed,stabile pivot),falling between two gravitational levels ,can release  the tangential component,only.

    A Milkovic's arrangement (with a mobile pivot for pendulum).when falls between the same gravitational levels,can release the tangential and radial components.

    If we develop pendulum-lever system,into a pendulum -levers system (a multi-stage structure,something alike Calder's "Performing Seal"),with a small swinging mass(pendulum),can we   stimulate the dymanics of a greater mass equivalent  ?!

    It's like a tree:a hanging small branch can move the whole trank.

    Here,again the input/output ratio is under talk...

        All the best! / Alex
