id like to build a model of this thing:
the thing is that the phrequency of the building has to be resonant with the phrequency of the pendulum
but i find four factors here that have to match:
lenght of the cable, lenght of the building, mass of the hanging weight, mass of the building, oh and a fifht, center of gravity of the building
also the building wont vibrate, just balance, something like this:

(to see this you have to wait ten seconds and then click skip add?
any suggestion on how to build this thing?
edit:
i find this mechanism extreamly interesting since its a double pendulum non chaotic
