Atwood's connection...

[iacob alex]

  ....can be an important step,so to imagine a possible PM.

     Again,at:    www.msu.edu/user/brechtjo/physics/atwood/atwood.html    you can find a "play-ground" address ,to understand so easy the value of the time factor ,for a torque avalanche ,in a gravity fall evolution.

    All that we need :

     -to replace,in the torque relation,the mass difference with the arm difference

     -to imagine "something"...a cyclical,self-turning scheme

     -to "recognize" the specific task,function of the rotational inertia/flywheel/heavy hub/massive "pulley"...as in the "Atwood Machine with a heavy pulley" ,this evolution of an old physics lab-demo,into a  new smartly intuition, on net

          All the best! / Alex
