The debris he hits before the splice looks like old rip cords from previous jumpers. I was really expecting a large portion of the hook to be missing when he slowed down but I guess it was more durable than I gave it credit for. Although his hand was pretty hosed up from trying to brake, I don't want to think how much embedded metal slivers he had to go get removed.

Why would he take his gloves off then push off and futilely attempt to brake with his hand ?!

Same. How do they put up a cable like that anyway? I'd always been curious about things like that in general, but I've usually only seen it in places where some actual construction had taken place, so I always unconsciously handwaved it as "they have money and science," but this wire doesn't look like it could have any other purpose out there than for hobbyists to climb and jump off of. The only thing I can think of is basically taking the whole length in a coil to one end, then walking/driving it out to the other end, setting up whatever equipment, then tightening at both ends until you have the tension you need, but I doubt that's how they do it. And poo poo, how do they afford that much cable? I'm bad at judging distances, but that's got to be a mile or so at least.

I highly doubt they put that up themselves. It's probably a relic of some industrial site or a valley spanning tram line or radio antenna or who the hell knows, its Russia. But to run a cable like that popular methods include: Tying that bitch to a rocket and shooting it across as well as the much less metal "hook it to a helicopter and fly it over" and more mundane ways like "cut a path along the valley floor, pull the cable then tighten it"

One possibility is that they dropped a cable down from each cliff, dragged the two sides together and then winched the entire affair up from both sides. Distance wise, the fish-eye effect on the lens does not help with that.

The trick is that you don’t start with the heavy cable. You run a much lighter line first and once it’s in place, you can attach the heavy cable to one end and pull it across. These days the initial run can sometimes be done with remote‐controlled helicopters. For the Niagara Falls Suspension Bridge, they used a kite. The Sidu River Bridge used rockets. I agree with the others that the cable was not installed for hobbyists, though.

kalstrams posted:Assuming you talk about 2nd video, teenager built his own x-ray source from two vacuum tubes he bought in a giant radio supplies market in Moscow. OSHA part kicks in to it's full extent after 1:30 in the video, when he puts finger under the beam. That finger got 25 sievert radiation equivalent and a 3rd-4th (4th is most severe in Russian classification) degree radiation burn. His right wrist got under the beam as well, and it also was damaged, but doctors were able to fix it. JFC, I didn't even realize that's what he was doing. I thought he was just putting a stick in the beam or something. Now that I look more closely, the shadow shows the bones inside his finger.  I really hope that the blue glow is because he's holding up some kind of phosphorescent paper, and not because he's created an x-ray machine powerful enough to produce a visible image without any kind of sensitized detector  e: I looked it up and if he really received 25 sieverts, he slots in between these two incidents quote:21 Sv: fatal acute dose to Louis Slotin in 1946 criticality accident[45] and the immediate dose rate is in the range of grabbing onto a spent reactor fuel bundle  Do you have an article about this incident?

Ah, thanks. Google Translate is plenty accurate for an article like this. Looks like the tubes he found were designed for doing x-ray analysis of materials (welds and the like, I'd guess). It says that the doctors were able to save his "hand" but nothing about his fingat specifically.

It says that the doctors were able to save his "hand" but nothing about his fingat specifically. Yeah stuff used for X-raying or radiography of welds is no joke. Guy put a little radioactive "pigtail" in his back pocket. Iridium-192 source. Ridiculously hot. He lost his leg. http://www-pub.iaea.org/MTCD/publications/PDF/Pub1101_web.pdf :mms: "When the welder arrived home at approximately 22:30, he reportedly com- plained to his wife about the pain and she looked at his posterior right thigh and noted a red area of skin. He took off his jeans and, with the source still in the pocket, placed them on the floor. He visited a local doctor who told him he had an "insect bite" and that he should put a hot compress on the area. The welder's wife meanwhile spent about five to ten minutes squatting/sitting on his jeans while she breastfed their 18 month old child. Two other children who were at home, a girl of ten and a boy of seven, were about two to three metres from the source for approximately two hours." "At 01:00 on 21 February, the operator of the company arrived at the welder's home and asked whether he had seen the source. The welder went to the bathroom and carried the source in his hands to the door. The radiographer told him to throw the source onto the street, after which recovery actions were initiated."

Drunk Driver Dad posted:hey, those are the exact sort of coils I make, it was neat seeing them put into place. Thanks! Anything we have over 4160V uses VPI, where you take the windings and put them in a vacuum tank to suck all the air out and replace it with some kind of varnish or epoxy or whatever. I think it was class H insulation for a 185 degree C rise. I think there's also this extra layer of black "corona tape" that I saw these guys using for motors or generators above 4160V. Rewind shops that repair and build motors are amazing. There was this one motor sitting there from a steel mill that must have been 16 feet high and 16 feet wide. I think it might've been for a blower or fan, and I don't think it was more than five or ten thousand horsepower, but it had an extremely large footprint. Oh and by the way if you see wires that are marked as "current transformer secondaries" NEVER disconnect them while there's current flowing through the primary. You'll get a fireworks show like you cannot imagine. Three-Phase fucked around with this message at 02:00 on Nov 30, 2015 |
