Scratch Monkey posted:I don't think it is, technically. I believe how it works is that EM field of the transmission lines ionize the air and that makes it a good enough conductor that when you touch something that is touching the ground you can get a shock. When I was a kid we had a cool set of bike trails that were under some lines and we'd regularly get shocks by touching our bike frames. I think what they mean is that you'll feel as if your hair is trying to stand up. With static electricity, that's because your hairs are charged and repelling each other.  In this case though, your hair will stand up because there is a big difference in electrical potential, and the charge on the wires is trying to find a way to ground. Through you.

The Lone Badger posted:I would have guessed it was induction. It's neither induction nor ionization. It's just a voltage gradient. There is a very high voltage in the wires up in the air, and at the ground the voltage is 0. That means that if you were to take any two points in space below the wire that are at different heights, you would find that they have a voltage difference between them. That difference between your head and your toes when you walk under the wire is what you feel.

Kenning posted:I am curious about the tingle. There is a set of high voltage lines at a golf course I went too many, many years ago with my dad. When you walked under them, I heard a hum and got a headache. No one else in the group did. Talked to someone at the course and there are employees that quit because they can't stand to be near them.

DelphiAegis posted:I'm no expert, but the tram driver is at fault on this one, right? Depends on the law. In a lot of places, running sirens and lights doesn't give you right of way, it's just a warning, and if you run a red light and get smacked the fact that you were alerting doesn't mean you avoid liability. In other places, there is a duty to give way.

What could they even do? Keep dumping tons and tons of sand/dirt into a sinkhole hoping it won’t…sink too much more? Genuinely asking here, I have no idea how sinkholes are fixed/fought/whatever.

You put a layer of asphalt on the pothole to seal it, so water stops getting in to erode the subgrade. The best way to fight a sinkhole is not let one form in the first place - maintaining the structures that channel water away from the bits you don't want eroded is dirt-cheap compared with fixing the damage later.

I think he was more saying what happens if the foundation is compromised and it's too late to pave over the hole. I'm curious too. Can't imagine you can safely brace the foundation before you shore it up, figure out the erosion problem, fill it, repave. I assume demo and rebuild.

Can't imagine you can safely brace the foundation before you shore it up, figure out the erosion problem, fill it, repave. I assume demo and rebuild. Sink holes form as large caverns, often in limestone, due to running water. When the top is finally too thin to support the load above it, it breaks through. Then you've got a small hole in the roof of a large cavern, which rapidly expands to engulf everything above it. There's not much you can do except keep people away until it's done eating.

Then you've got a small hole in the roof of a large cavern, which rapidly expands to engulf everything above it. Yeah this is the half answer I expected and theorized. You just let the whole thing collapse, demolish what you can first? Then rebuild with the new foundation? I assume that means you'd still have still deal with the water problems. I could see how letting the building materials drop would help fill in the hole, but I'd expect that to be temporary given it's just a debris drain and not intentionally constructed...

I like that warning sign because the first time it happened to me I thought I was about to be struck by lightning or something. I'll never forget using a small boom lift under some high tension wires, it took me the entire day to realize that the metal wasn't covered in sharp splinters that kept pricking my fingers, I was getting zapped.

The corvette museum in kentucky had a huge sinkhole open up underneath it. They just put in a new foundation and plugged up the hole. Granted they have a lot of money and it makes the museum a little more interesting because they have a special attraction added to it now.
