Tumbling pendulum...

...can be an evolution of the well known "tumbling toy":an apparent "stick" form(light empty tube sealed) will tumble and roll end-over-end when on a ramp or incline,as the gravity pulls at the heavy steel ball hidden (inside) .Something as a "wheel" on an inclined plane,but in a "tumbling manner".On a plane surface it will not move.But...if we introduce inside a cylinder box a "tumbling pendulum"(one of them as "Gravity Flip-Flop",at   www.geocities.com/iacob_alex/Stellarotor.htm    see New!New Drafts! pos. 3) it's possible to realise a new point of view.The friction circumstance is helpful...This instant,a longer free fall time  and the long arm-short arm torque difference ,not the iron ball act as an energy imparting falling elements.The resultant moment of the gravity that imparts torque on a tumbling pendulum ,is comparable,looks like  the fluid flow material that loads a watermill.The "tumbling toy" on incline and the "tumbling pendulum" on surface,have some common appearances:falling in gravity.Half the work seems to be done when we make the things to appear alike.All the Bests!/Alex

...of a pendular fall in the gravitational potential field can be a reality.A sequence of events(fall-rise of the well known clock's pendulum) is called isochronous if the time separating each pair of succesive events(fall-rise ) is strictly equal."Old fashionated" pendulums make good timekeepers because they always take the same amount of time to complete each back-and-forth swing,keeping clock turning at a steady rate.The  absense of isochrony is called anisochrony.Anisochronic state represents accumulations and delays(as a charge-discharge delay network  in electronics).Gravity fall(material flow) is isochronic thinking about a pendular swing.Can we control this time-delay system?Yes,if we engineer,control,play on it(pendulum) in a particular manner.Let's say that to a half turn(180* fall)  follows a next fourth turn(90*fall,moreover..self-switching the long arm-short arm ,that's the point!) and the last fourth turn(270* to 360* is the only time-gate for rise/"remake").So,can we make this gravity fall,flow anisochronic with a self rotating variable counter-balanced pendulum?Long time ago,the so beautifully persian watermill/noria hypnotized some people,so they intended to transfer this "imago" in the gravity fall as an overbalanced wheel.But,in the end,this wheel ,has as an concise symbol(equivalent) a somehow balancing ,yet stable (up fulcrum...)  lever(two opposite spokes...).If we pay attention to some wall paintings from the Middle Kingdom tombs(Egypt) that shows a method or raising water with a counterpoised bucket at the end of a long pole(the Shadoof),we can think that the "minimal wheel" is the lever.Shadoof was and is now in the poor world,a "heavy" machine,a first class unequal lever used for lifting water.The problem is that it works with an almost effortless swinging  and lifting motion in gravity,so it can be a starting point to meditate about "wheel vs. lever" in that "perpetual" quest of free gravity power.So,have we  an another "imago",that we can transfer in the gravity fall,as an continuous  overbalanced/unstable lever?Science is a progressive discovery ...and we are on the way,not at the end.Man must go back ,again and again,to nature for information.All the Bests!/alex
