I was wondering is there a way to connect two rotating cicrcles

[beedle bard]

guys, I'm new here. please forgive if I'm a bit clumsy or act like a fool.

i was wondering how do you connect two rotating cicrcles. specifically, suppose there are two huge spherical disc( torus). there is a distance of, say, 500 m between them. both are rotating at their indiviual revolutions. my question is: how do you connect them

i don't want them to stop rotating ( minimising friction, of course). i have no idea what method or technolgy would be use for this process.

specifically, i request you to consider this scenario in the light of space settlemnt( stanford torus).

kindly help me.

Welcome to PF, Beedle.
Your description is a bit vague, but it would seem that a simple slip collar would suffice. The tubular axle of one wheel would fit inside (with seals and bearings) the slightly larger axle of the other wheel.

Danger, thanks for the reply. but i think that you misunderstood my question.

the toruses are lying adjacent( must be connected in a series) to each other; they are not parallel or within each other.i don't want to fit them within each other.

i'm trying to upload a picture from my computer, but i don't know how.

please help.

Do you mean, then, that it would be like two doughnuts lying beside each other on a table?

exactly.

moreover, the doughnuts are colossal (say, radius 500m), the distance between them is 100m and they are stationed in space.

Do you want a rigid connection or flexible one?What are the desired degrees of freedom?

i think it should be rigid. basically, the connection should not hinder the rotations of the disc and allow to them to rotate simultaenously; while keeping them in place.

The most appropriate thing that I can think of would be to use a '[' shaped connector with one of the aforementioned slip-collars on each leg to mount the wheels. If I recall Gerry O'Neill's L-5 proposal correctly ('The High Frontier'), a hollow triangular beam would be sufficient for both strength and rigidity.

guys thanks for your help, the situtation has been resolved. so mod can you close this thread?
