...full of fun,gamesome and witty you can find at http://www.mcachicago.org/Book/Calder-txt.html
The well -known "Performing Seal"-1950 ,of the famous Alexander Calder,an American forerunner of the dynamic sculpture,it's more than a genial mobile-shape...it's a living lesson of dynamics in gravity and inertia.
You can play so easy your model,with wood(sticks),metal(wire).
"Performing Seal" looks as a circus seal balancing a "special ball" on its nose/fulcrum,at any slightest unbalace/breath of air.
So,for the moment,make one and have fun.

....you can see at www.mcachicago.org/Book/Calder-txt.html , can we to take up as a Milkovic's multi-stage arrangement!?.
Now,if we test a such kind of many level oscillator,what will be the output/input ratio?
If you think that Milkovic's pendulum with a lever is questionable,regarding the output/input relationship,this "Russian Puppet"style of the same oscillatory phenomenon,can be a proof?!

Hi iacob alex,
Thanks for the link, I have seen his work long ago. Indeed Calder's work is a balancing act of beauty and ingenuity and I see the same in your work. Good luck in your research.
Take care,
Michel
Hi Michel!
Calder's "playful seal'',among many other his mobile sculpture,is intended to mimic the fun game of a seal with a ball,at circus.
At circus,we can admire the sensibility and dexterity of a fatty animal...
With Calder,this "creature" becomes inertia...because any gentle wind is an input,and the output is a marvel spectacle.
I look at this,as an invitation to reconsider inertia,like a fish in water:a huge basic unknown world for mechanics.
