Heavy hub pendulum...
« on: August 01, 2008, 12:03:25 AM »


....can make a correspondence between an Atwood Machine with a massive pulley,and a pendular mass with a heavy hub.

   A small mass difference(Atwood machine with a massive pulley)  is engaged to coil,spiral,gather the gravity fall into a great rotational inertia,in a retarded motion.

   The heavy hub pendulum(or a long arm-short arm configuration with a massive hub...) is intended to operate alike.The hub works as a temporary energy storage.

 ....  can be a landmark,to understand the connection and energy transfer,between gravity and inertia

    In this simple design,picture we have a fulcrum,an arm and a mass operating in gravity(as a classic lever...),but...the other "arm" is  "void",only a massive hub,the central zone of the rotational motion.
 
    As a whole,the image is of a heavy hub pendular mass:it can transform a translational pull of gravity(arm and pendular mass),into a spinning  motion on the spot(fulcrum...),so into rotational inertia.

    It's  something apart...a lever in two "worlds":gravity and (rotational) inertia.

    The input is in gravity.

     Now,how about the output!?

   ....is imagined to store rotational inertia,due to a pendular fall in gravity.

       Look at :   www.msu.edu/user/brechtjo/physics/atwood/atwood.html   

       The simulation-test was made for a particular Atwood Machine: with a heavy pulley.

       If we use the heavy pulley (M3) as a heavy hub for a pendulum (arm+bob M1),we can roll up gravity fall (this time with a variable arm...).

       The interesting point is that,we can accelerate a heavy hub (rotational mass), with a very small falling mass...as a large wave rolling onto the shore...

       And more...we can manipulate this "wave",in a short discharge,so to close the loop (to get a "self-motion").

   ...is an abstract concept.It can be applied in many circumstances.

      Let's make an exercise of science-fiction.

      So,we have:

       -a horizontal surface

       -a perfect disk shape huge mass,of the size of a... mountain

       - you...on the top position

       Now,if you have  some "free-time" (patience...),can you move this "mountain"(just remaining on the disk surface,on the same spot,nothing more...),so to get out  some "free-motion", with the "price"... to climb again on the top?!

       Remind,for the moment is science-fiction,only!

     Hi !

  A first degree lever,usually consists of a rigid bar,free to move about a single point.

  It can be a long arm-short arm shape,placed in the gravitational field.

  If it is set free,with the long arm in the top position,we have an unstable condition,it's a free inverted pendulum.

  When the lever is released,it begins to accelerate,due to the arm difference:the resulted acceleration is much less than the acceleration due to gravity.

  Here we have the same case,as an Atwood machine with a heavy pulley...

  An ideal gravity "mill"  can be imagined in an easy design,as two unequal arms of a lever,with a heavy hub,and a simple switching procedure.

  The main point is, this switching operation,intended to expose( "remake")  the long arm, on the same side of the fulcrum/pivot.

  The  "retarded" fall can be stored in a heavy hub of the lever,as rotational( "on the spot inertia") motion:gravity power moves ("flows") into inertia power.

  As in an Atwood machine with a heavy pulley,this time,the heavy hub is a slight change for the lever,only...

  The assumption is that the (curvilinear) fall "gives" more than "takes" a vertical  "jump up".

  Pay attention:"jump up" is not an "m*g*h" interdiction (you know the theory...),but an "distant action".

  This switching procedure,can be your finding out,from beginning to end...

  .....is imagined to make slow a swinging motion,to retard it.

      The bob-rod torque will rotate the heavy hub.

      The heavy hub is working as a resistance and power storage system,in thew same time.

      Simply,we slow down the gravity fall of bob,between two gravitational levels (potential energy) and store this motion in a rotational inertia "basin") kinetic energy).

      Why? Maybe, we can use this  "vague" idea further...for our topic.

        All the best! / Alex

  .....in a certain way,can be considered a "relative" of a hour-glass (container in which sand drops through a narrow passage,formerly used to measure time),or a clepsydre,if we have in mind to measure time,due to fall of the "stuff" in gravity.

      Also,the heavy hub pendulum can be considered an "extreme" imaginable pendulum.

      The same image "meets" an another imaginable simple machine,a class 2 lever,if the load moves in the pivot point,as a heavy mass ,and the effort is the gravity fall of a mass at the other  end of the bar/stick..

      So,a certain pendulum comes face to face,with a particular lever in a common image...

     Can be this useful to our topic?!   Maybe...

        All the best! / Alex

.....for the present moment,is an abstract idea,but a possible real "clepsydre" of time (and motion...especially!),also.

    We can make easy a correspondence between a heavy hub pendulum ,and a natural PM (that cannot be refuted!) :

       -Sun /fulcrum,pivot.

       -Earth/great mass,central massive point,heavy hub.

       -Moon-satellite/pendulum's bob.

       - constant distances/gravity links.

    Anyway,if we "fly around" the Atwood machine with a heavy pulley,in my opinion,we can have a certain starting point,to imagine a real,small "copy" of the natural PM.

       All the best ! / Alex
