Safety Dance posted:This is probably a horrible mechanical failure being prevented, but I thought the sheer power involved fit the theme of the thread. I was at a coal plant that did that when they started up. IIRC it was to flush air and liquid water from the tubes and steam drum after service. It was painful from over 200 m away, even though the plant was pretty low pressure (1800 psi) and the outlet was fitted with a suppressor.

Dick Trauma posted:Amazing and horrifying 8 minutes of street cars and motorcycles wiping out on the Nurburgring Nordschleife back in 1970. Engine bays are vomiting up their contents, glass pours out of frames and drivers are ejected like James Bond just pressed his little red button. Does upholstery unhook that easily in modern cars?

TotalLossBrain posted:It is unfortunately fairly "common-place" for radiography sources to do this kind of damage. They are usually Cobalt-60 and put out ungodly amounts of gamma radiation. Normally housed in a shielded carrier that gets opened via a cable just for the exposure. Sometimes it gets left open, sometimes it falls out, gets picked up by others, etc. I worked at a coal plant that had cobalt 60 sources for measuring the level in the coal silos, and there was a dead-serious certification/recertification process with the NRC for the person in charge of it. Absolutely the same level I see now that I'm in the nuclear industry.

TotalLossBrain posted:Well okay....I suppose SL-1 was a criticality "accident". There were rumors from people who knew those involved that said it was a love triangle gone wrong and the removal of the control rods was in fact not accidental. Hard to say now. The love triangle story is so ridiculous that it should have been rightfully forgotten by now. Also, SL-1 final rod maneuver would be termed a reactivity initiated accident (RIA). Hypothetical RIAs, like the ejection of one or more control rods from the core, are the kind of hypothetical event that people design all reactors (and their safety margins) around. SL-1 was no exception, but the behavior of the core changed as the affixed neutron poison inserts (which serve as a kind of permanent brake on the rate of reaction) came loose from the core. It should not have been possible to begin with. It was negligence that allowed it to get that far.

veedubfreak posted:Some fuckhead out here drove down the shoulder of 225 on Tuesday during rush hour, sideswiped multiple cars, caused 4 separate accidents, then abandoned the car at one of the light rail stations and got on the train. The car was registered to him. This is the kind of stupidity that makes me lose hope in the human race. Is there a term "statutory DUI"?

I'm still angry about the bulbs not having enough contacts (?) on a 2001 B Sprinter's rear light cluster. Nothing to add, just needed to get out. It just broke confusingly.

So I remember the jokes about the oil change schedule on VW TDIs being like owning a two-stroke Trabant. Is that level of oil usage just normal for everyone now?

Messadiah posted:Sorry what, please elaborate US trailers: Trailer hitch on a ball mount (usually), with chains to keep the trailer attached to the vehicle if the hitch pops off.  EU trailers: Trailer hitch on a ball mount (usually), with a panic line that fully activates the trailer's brakes (before shearing off) if the hitch pops off. I can't see why the US version wouldn't just leave you with an uncontrollable car because of the swinging trailer (if the safety chains are under tension) or an uncontrollable car because the trailer's rammed up against the back of your vehicle (if the safety chains are under "compression"). In the EU version, you at least separate the dangerous part of the system from the passengers. It doesn't seem like keeping the trailer from separating should be its own goal -- either way you've got a bunch of unexpected objects standing still in the middle of traffic, in the end.

The Door Frame posted:Any time a poster says anything about actual requirements in their driving test, I know they aren't American without looking at who posted it. I had to do a hill park during my test and if it ever gets brought up in conversation, everyone in the room gets surprised they tested me on something so difficult I've gotten my driver's license in the US, and multiple licenses in Sweden (some of the lowest pass rates and highest cost in Europe), and the driving test isn't significantly harder. The road design in the states I was in was simpler, but not that much. The real difference was the theory test. I've had final exams in engineering courses that required less studying. And you have to do it all over for each of your other licenses (e.g. motorcycle, heavy trailer).

evil_bunnY posted:what state? how long was the test drive in each case? Nebraska and Illinois. I'd say about 20 min of actual driving in both cases. The road design is easier, but the actual tasks we had to accomplish weren't that different. I didn't even have to parallel park in Sweden. But, as I said, the theory test was massively more difficult in Sweden. And it definitely made me a better driver than I would have been, if Sweden and the US had driver's license reciprocity and I didn't have to redo everything from Square One.

Invalido posted:It does require the risk2 low friction skid course thing though, surely that counts as training? The state of Nebraska issued drivers between 16-18 years old a "provisional operator's permit," but requires them to either log 50 hours of driving practice with a parent, or go an approved driver's education course (no such requirement exists if you wait till you're over 18). That's the only time I came in contact with a training requirement in the US or Sweden.

UCS Hellmaker posted:Bp at some stations has the pumps switched, everywhere else it's green for diesel, seen a few bps where gasoline was green and black was diesel, all on the same pump. Almost hosed my wife's car up because of it before but caught it because the nozzle is bigger. Is the nozzle size standard universal? Or is there e.g. an EU standard, a DOT standard etc?
