    I’ve been there, it’s pretty crazy. There are a bunch of anti-government rants in front of the entrance that you can’t see from this picture, so this place has a pretty weird vibe.

      It is extremely sound. It is build from granite and concrete and the foundation is sitting on solid granite so it isn’t going anywhere. The metal portions do swing a bit but that’s normal since metal naturally is flexible. However, all of the welds are professionally done so it isn’t going anywhere. Honestly I think the structure will stay solid for a few decades at least. The son is making repairs as needed so it probably will last much longer.

        What is not flexible? There are springs made from tungsten carbide.

            And you are telling me those are less flexible than tungsten carbide? They are rubber in comparison. Young’s modulus for WC is 550 GPa. Granite is about 70 GPa and concrete about 30 GPa. Oh, steel is at 200 GPa.

            So what is the actual reason you see metal flexing when it is actually far harder to flex it?

            1. Much smaller cross section or specifically second moment of area while very long.
            2. Nothing, there is only that one reason really. Things get very easy to bend once they get thin and long.

      He worked on it for 75 years. (Age 15-80)

      He probably was ripped at some point but when I met him he was old but still kicking
