The thinnest structure in the world?
 

I do not know where the guyed mast shown on http://www.youtube.com/watch?v=NwkB9QTKVw4 stands, but it seems to have just a cross section of 2 metres. If it is really 540 metres tall, than itsheight:width ratio would be 270 :1! Do you know a thinner tower-type structure?

I have no idea where it is, but it doesn't seem smart climbing up there with the dark weather surrounding!

The narrator mentions OSHA, which is American (Occupational Safety and Health Administration), and there is an array of similar height towers around it, plus one much taller.

I'm guessing this is in Nebraska, or possibly South Dakota.

For a list of guyed towers in the US try this;http://en.wikipedia.org/wiki/List_of..._United_States

For the rest of the world.....I'm not sure.

Here's a similar question. How wide are those guyed towers usually?

Carbon nanotubes structure would be even thinner.

First of all, I introduce yourself that Jesse, today I just joined here, I was just a working person, do not have what experience, hope can and everybody mutual communication, give me some Suggestions, thank you:notacrook:

How thin is the KVLY TV-Tower in North Dakota and how thin was the Warsaw Radio Mast?

For Warsaw Radio Mast I knew it had a triangular section with 4.7 metres side length, which was constant for the whole structural height.

i'm pretty sure these guyed masts you guys(no pun intended) are talking about are hundreds of feet wide.

If a guyed mast was hundreds of feet wide it would be a large steel square...

um.. no i meant that the guy wires are an inseparably cohesive part of the structure... so why wouldn't they count in a measurement of wideness? thats like saying an elevator shaft of an office building is so thin without counting the surrounding structural contents.
