Title: Inertia against gravity...
Post by: iacob alex on December 09, 2008, 02:31:08 AM

  ...or more explicit the rotational inertia of a  heavy hub/rim opposed to the gravity fall of a mass(torque difference,in fact),between the same gravitational levels,can be a way to store more and more gravity power(the process appears to be a longer exposure of an unstable arrangement to a continuous and accelerating phenomenon),so to release,then, enough power regarding the friction,the "remake" of the starting shape and sure,our own demand for "free" power.

     It can be seen as a new leverage deal with:one arm in gravity,no arm in rotational inertia...

    The proposal is to make use of the spinning inertia as a temporary ,transient storage for a longer time gravity fall,retarded gravity drop of an unbalanced system .

    If you like,it can be  the image of a pulsatory flywheel,as we can see all over around us,thinking in the terms of the natural mechanics.

    It's an usual ,up- down game with inertia,nothing more...

    The main point is the possibility,to wrap up in a self manner the gravity power.

When placing an extra mass on a balanced wheel you exert a force F upon the wheel that works for a much longer time (change in t) upon the total mass of the wheel. F = ma (a = change in v / change in t) or F t = mv.  The velocity (delta v) of the wheel results in a very large quantity of momentum. When the momentum is transferred to the unbalanced mass the energy is increased tremendously.

So I think your statement is correct.

    ....or a common,newtonian relationship: action=reaction.

      Now,as the case may be...longer action=greater reaction?!

      Action is the gravity fall.

      Reaction is inertia.

      Gravity fall of a system(a pair of unbalanced masses) is retarded,temporized(as a "parachute") due to the connection with a balanced massive mass,settled to "coil" the drop in the gravitational field.

      The balanced massive mass is now ,that "fixed point" (insignifiant mass.. .) of the classical mechanical clocks ,but now storing the rotational energy.

      If you like,let's say that we play a new type of pendular movement:slow-paced,tortoise-like.

      A different,unusual(but useful!) pendulum...that's all.

      A small,but time extended unbalance(action), becomes a source of a great push to inertia(reaction).

      We are slowing up,delaying the fall as in a simple fluidic flow,when we are intending to get out some power.

      The purpose is to store enough energy,so to release then it, and build a self process.

      So,if we play this new pendulum(bob-arm-heavy"fixed point"),maybe the imagination will help us on our way to design a free energy "toy".

You are correct: A one kilogram mass freefalling one meter gives you 4.429 units of momentum and 9.81 joules of energy, d =1/2v²/a and Ke = 1/2mv².

A one kilogram mass accelerating a vertically mounted ring (for one meter) with a mass of nine kilogram has 14.007 units of momentum, and if all the motion (when the one kilogram reaches the bottom) is given to the one kilogram it will have 98.1 joules of energy and can rise 10 meters.

The cylinder and spheres experiment has proven that you can give all the motion to the one kilogram, so it is all about building bigger and bigger machine.

   ....can be easy understand,as an interesting process,with the help of  a lab-demo  at      www.msu.edu/user/brechtjo/physics/atwood/atwood.html   

       I pointed about this,some time ago on this forum.

       As I see,Pequaide was interested about this.

       Good news,because the curiosity can be the first step to overcome our lack of knowledge.

       As somebody  a time ago noted(Karl Popper-1960) :"Our knowledge can only be finite,while our ignorance must necessarily be infinite".

        So,this lab-demo can be for some people as a "mind sparkle" for a second step...!?

    ...is based on the simple fact,that gravity has no inertia for a natural,vertical free fall.

       For a different trajectory of a gravity fall (let's say one curvilinear...),we "meet" inertia.

       All that I made,was to settle,compare  a  vertical free fall,with a rotary free fall.

       Can it help this topic?

   ...performs,everytime when a body falls on a different trajectory than the vertical line : the gravity must do a greater work,than on the vertical line.

      The reverse of a
 vertical free fall,can be a jump-up motion.
      So,making a balance,correlation between a vertical free fall in gravity,and a fall on a different trajectory,but amid same levels,we can mesure a kinetic energy difference.

      The next idea is to use it.

.....or more precisely rotational inertia suggestion , as an extremely strong "wind" something alike :

When we like to wonder...it can be a seed to understand.

hi,
that link atwood.html on msu is 404, is there any substitute?

.....let's try as a substitute , at :
     http://demonstrations.wolfram.com/AtwoodsMachineWithRotationalInertia (http://demonstrations.wolfram.com/AtwoodsMachineWithRotationalInertia)
     Here , to store energy due to gravity unbalance , as much as possible is a main point for a massive pulley.
