a segment on the ground can go to a maximum of around 7km using regular steel. There are no ends on a ring though so the weight is evenly distributed around the ring... ground is the problem as it is a vertical force. With a ring there are no vertical forces, just the rings own self weight

but yes a section of the same bridge could easily cross a valley

Same with heat expansion and contraction, wind and seismic... can you answer the question, ignoring all other factors, or you’re not sure? Two half circles pressing into each other or the table model? No, land bridges touch the ground whereas an endless bridge does not. Bridges are limited on...

Nah

What about it?

Hi, I’ve got a question. it seems that engineers, structural mainly, don’t seem to understand how gravity works regarding an endless stationary (steel) ring/bridge around the equator. Many if not all have said that such a ring would be modeled as two half circles pushing into each other. So the...
