How is it tensegrity with rigid bottles used as support?

[–] Ddhuud@lemmy.world 8 points 11 months ago* (last edited 11 months ago) (1 children)

Tensegrity, tensional integrity or floating compression is a structural principle based on a system of isolated components under compression inside a network of continuous tension.

The bottles are in compression, while the tensors are providing... You guessed it, tension.

Tensegrity usually means integrity from primarily tension, like cables used as the main struts for something. This just looks like it's bottles as a structural element with rods preventing them from coming apart

I don't know that I would go so far as a describing it as tensetrity, but the majority of the load on the shelves is held through the I/J hooks in between the bottles. The bottles are there more for stability.

Those are just pulling the shelves together and putting more pressure on the bottles.

This shelf is designed with "sit in a chair and fly by lifting the chair" logic.

[–] InquisitiveApathy@lemm.ee 3 points 11 months ago

I think we're in agreement in both those regards.

I meant stability in the sense that it's preventing shelf rotation. It does the job I guess, but I don't see this being a particularly long-lived piece of furniture.
