PM "gymnastics"...
« on: March 09, 2013, 11:52:50 PM »
...of your body ,at : www.youtube.com/watch?v=R2mpYJA1-iU   (from 0:10 to 1:10)


can help your mind, to get free from any head-ache regarding the simplicity of a gravity motor principle.


This is the "classic" variable arm (hinged arm) , so easy to play a continuous unbalance...


Remind the Middle Ages designs (Taccola , da Vinci, Bessler...) ,but make an attempt  to imagine a lever,a seesaw...so, not a wheel ( www.youtube.com/watch?v=ohap0KAo7kE

Simply,a wheel concept "suffocates" the main workable feature of gravity fall ,that can help us to obtain self-motion...

Try to make a direct connection with :

Hira ichimonji no kamae

now that you introduce the concept of intimately knowing motion i suppose it is appropriate to indicate now ..that , by feel, the two weights most move in the manner of hira ichimonji no kamae (i.e. migi to hidari to ka)
the decipline is very old and very detailed, a glance at the video probably will not be sufficient to show the way to the exact motion i am refering to
 
as for besslers wheel.. there were many things in my life that led me to the solution
not the least of which was work with an uncle who happened to have an old tool for weighing cotton
my own father had worked picking cotton in the fields of texas for $0.08 a day back in the late 1930s
at the end of the day was this damn scale.. like a nike check with a metal ring near the check hook
hook the loaded bag and move the counter weight to the notch to find balance and find the weight
it was fresh in my mind when i first found the picture of besslers wheel and began to sort its detail for comprehension
 
left..
and right..
 
typically i see the wheel from a side view
i suppose i almost always visualize it as rotating counterclockwise
down on the left and up on the right
 
i really do have it sorted out to completion
the path of least resistance.. has no stoping point
 
understaing how one system works has led me to comprehending several other systems that happen to have enough data exposed
 
the finsrud device is spring powered
..this having everythig to do with angle of contact of the spring and nothing so great from the magnets other than a temporary gain of reduced friction
simple as that.. even if the method to single out the correct focus for comprehending it is not so much so
 
the keeny wheel is a coil spring that winds itself and stores energy as it does so ..all this due to its ability to discharge only 1/4 of its stored force (per cycle) to move a weight and reset the system that eventually returns to the position where again only 1/4 of the stored energy of the most recent cycle is sufficient to reset 
 
only the asa jackson device is outside of my understanding due to its lack of assemblage

.....topic ,is an allegory,a description of one thing under image of another.
     Such,the gymnastics of your body on a inversion table/beam/lever can help your mind to simplify the things.
         www.youtube.com/watch?v=mYbT9M6KaO0
     So easy ,you can play an unbalance on a lever, moving your hands,only...like a fish in water.
     Something like that , a lever + two masses can reproduce this unbalance.
     The key word for a gravity motor is the unbalance and how we play it.
          All the best ! / Alex

.....of your mind , imagination if you take a look at :
     https://youtu.be/6NG6Y5aKN0w
Finsrud's building /machinery has a clear track , but a sophisticated "attachment" .
A clear ( closed...) track with no "attachment "  can be a real challenge , if we find a manner to play gravity and inertia , as :
