Kiiking toy...
« on: January 10, 2020, 12:00:27 AM »
.....if you take a look at : https://giphy.com/explore/kiiking
     Now we can play an abstract mechanical equivalent model ( mass spring system on a pendulum ) , as :
     https://youtu.be/z6_NRNw88Jw
.....but with the starting position on the top ( as an inverted pendulum ) , so to introduce an asymmetric 
     "assistance" of the rotational inertia (due to the spring in-out storage ).
     This interplay of gravity with inertia has as a result a "self" continuous  accelerated rotation?
.....with an elementary test...we have an answer.

  Hi
  As a matter of fact we have an elastic pendulum(human performer ) attached to a common pendulum (seat and bars) playing not swinging,but a full 360* rotation.
  Elastic pendulum at : https://en.m.wikipedia.org/wiki/File:2D_spring_Pendulum.gif

.....starting with the elastic pendulum theory , at :
     https://en.m.wikipedia.org/wiki/Elastic_pendulum
     As a simulation , step by step , at :
     https://www.myphysicslab.com/pendulum/pendulum-en.html
     (Swinging arms and seat/a rigid,non-elastic pendulum)
     https://www.myphysicslab.com/springs/2d-spring-en.html
     (Pumping person/spring mass)
     https://youtu.be/z6_NRNw88Jw
     ("Kiiking"/tumbling mass/spring mass system on a pendulum)
     Now , we have a simple toy:we can play this one as a swinging one , or as a rotating one (if we start as an inverted pendulum...and search for a "skillful pumping"...or a "self" tumbling/rotating amusement "appearence"?!)
