Deformation of a device

[EOW]

all volumes are constant, the deformation of the white disks don't give nor take an energy.

[EOW]

I use the bottom wall and the left wall to cancel the force on the bottom white disk. The bottom white disk has all the force from the others white disks. I deform the shape of the white disks when the container is deformed but I keep constant the volumes. The top of the container is fixed to the ground. The green line like the bottom of the container move to the right.

[EOW]

no need to deform the white disks, the white disk A is taken by the walls directly, no spring for the white disk A.

[EOW]

Even an object there is a difference of energy

[EOW]

with another shape than a disk I have a lateral movement for the blue spheres
