Triangles, Bridges And Centripetal Space Habitats

AI Thread Summary
Using steel triangles to construct metal bridges is effective due to the strength of triangular shapes. Applying this concept to a bicycle wheel-like space station foundation could enhance its ability to withstand higher rotational speeds compared to an unbraced sheet of material. However, there is a maximum angular velocity limit for safe rotation, influenced by tangential and normal stresses on the structure. A strut system can help distribute these stresses, improving stability. Ultimately, while bracing with triangles can provide benefits, material limitations still impose constraints on rotational speed.

Making metal bridges from steel triangles is a very good idea because triangles are one of the strongest known shapes. My question is, would making a bicycle wheel-like space station's foundation braced with lots of triangles of whatever construction material is used(carbon fiber, aluminum, titanium etc.) make the space station be able to handle higher rotational speed without flying apart than using an unbraced sheet of material as the station's foundation?

To a degree this could help. However, there is a limit to the angular velocity with which a ring can safely rotate. There are tangental and normal stresses that are imparted on a spinning disk. So a strut system could help distribute the stresses due to rotation.

FYI: This is why you won't see a CD-ROM speed faster than 72x because that is the rotational speed at which the acrylic the disk is made from fails (and the 72x drives have a hardened steel case to prevent flying acrylic shards... of death).

Cheers...
 
Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
