play in the joints

[Dick Fischbeck]

I think in geometry it is imperative to consider, better an actual imperative, to account for  play in the joints, just like the courts themselves are talking about.

I mean, Blair, don't you have to consider play and stack?

I’m unfamiliar with this term

The term came up this week in legal Scotus arguments but I think it also applies in a physical way in domes. I am all for some slack or movement on dome vertexes but too much slack leads to turbiining  around vertexes. This might be a metaphorical stretch yet I like it. I'm just thinking-out-loud.

I mean, you, Blair, think about the tolerance of your dill hole and the bolts that fill them and how much play there is. Maybe this is a minor consideration to the overall strength of the dome.

[Ashok Mathur]

Don’t do all your thinking in terms of structures where parts are rigid.

Do also think in terms of a machines where parts move relative to each other.

The divide between a structure and a machine is artificial and man made.

Geodesic domes have attributes of both a structure and a machine.

Accept it and work with it.

Ashok
