Hello everyone, i m working on a full circle space centrifuge concept. I try to support it with some maths but i don't want to dive into crazy details. I used alrdy lot of countermeasures to dangerous effects.I have problems similar to bridge mechanics. The design is not solid so i need to be careful about many things.
The shape of my concept looks like a big cross (made our of wire ) on each end of the cross we have solid pieces metallic platforms, while 2 parallel circles of wire connecting the 4 platforms via "bridges". In the center we have a central hub. Hopefully this 4 bridges will be real solid bridges at some point.
The type of wires i picked is almost random, but I am trying to use some true characteristics like brake point.
My first problem was to understand how strong is my bridges.With help from forum i found the tensile force of a rotating full circle, and a second approach how much weight i can put per some x distance when the shape converts to an Ngon. So i produced some safety limits for example 300 Kg per meter of bridge at 0.1654 G.
---
But in reality there are no full circles of wire, platforms getting in between every 45 deg isolating bridge wires into arcs<45 deg does that affect limits?.
Also at the start of p2 the bridges are almost empty, and i was thinking of 8 vehicles that could start using the wires as a railroad, to distribute, materials symmetrically, but if something heavy steps on a bridge the shape changes only i don't know how.For now, this is the main question that bothers me, how the shape of bridges will change with distribution of materials. Can somebody guide my how i can simplify this problem.
And btw since i want to end with a solid and rigid full circle i want to distribute space-frame materials. Any suggestions have you heard anything similar space frame based on wires? For space it should be something lightweight and strong right?
