A "merry go round" test...

Their purpose is to play an asymmetric couple of "merry go round"s , so to obtain a tractive/transport vector ( inertial propulsion).
If we minimize this arrangement ( three masses,only) , and play the gravity accelerated unbalance , we can use a single continuous variable/oscillatory arm...so to test self-motion ?

Various attempts to build reactionless drives have all relied on stiction.  CoM is a stubborn thing.

      Hi !
In my opinion , there is a difference about how we play the rezultant vector of the couple (paired ) spinning eccentered masses.
Some people play it "to & fro"+striction , as :
  www.inertialpropulsion.com/the_dean_drive.htm      ...and others
...vis-a-vis the up here movie ("to",only...the idea is to play the rezultant tractive vector , on the same side of the fulcrum).
A lot of "old" experiments , at : www.geocities.ws/iacob_alex
Maybe, if I "speed up" some of them...
Anyway,it seems that the inertial propulsion and gravity motor have a common "starting" symbol :pendulum / eccentered mass.
This can "cover" the variable/oscillatory leverage method , for a possible gravity self-powered device/motor.

hmmm....

.....as a simplified asymmetric "merry-go-round", with two masses ,only :

     When thought is simply expressed on paper...it's easy to be experienced ,also.
