I was really upset until my older brother helped me turn it into a crash-scene diorama which was basically this... Showed me how to pin-hole bullet-holes into the wings, bend back parts of the skin and paint the inside silver, and gently soften the prop over a candle to bend it back....

haveblue posted:The main thing I’m curious about with the MRI is how the electricity gets to the spinny part. I guess somewhere in there are two motor brushes running along a circular track? 13 thousand-mile-long cable that just winds around until it snaps and the machine is quenched and decommissioned.

It's weird because unlike places like Vietnam were there's seemingly no rules when you're driving, they actually follow some sort of rule, then once the light changes it's just chaos.

Buce posted:13 thousand-mile-long cable that just winds around until it snaps and the machine is quenched and decommissioned. It’s a ct scanner so no magnets to quench. Having witnessed test runs of a ct scanner with its skirt off the most surprising thing is how quiet the device is. Until it isn’t, which was why service was there to begin with.

Horrific stampede in Seoul during halloween celebrations, maybe around 150 dead pretty stuff E: don't loving click it if you don't want to see the aftermath of an event where up to 150 people probably died https://www.youtube.com/watch?v=xRYHYWlMjW0 mobby_6kl fucked around with this message at 21:31 on Oct 29, 2022 |

Foxfire_ posted:For anything spinning fast or that needs to reliable, you don't use brushes because they are high friction and also wear out. You can do better by essentially unwrapping a transformer so that the primary and secondary windings are physically separate and can spin relative to each other. It can't pass DC, but that's fine. You also control both sides and aren't trying to move power long distances, so you can use higher frequencies (couple hundred KHz) where coupling is more efficient and the parts are physically smaller (mains transformers are chonky because inductors that don't saturate at 60Hz are big) drat, suggest people don’t click that… didn’t know they celebrated Halloween in South Korea but I guess I’m just dumb. Anyway, thanks for the effort post above re: rotary transformers. Really cool stuff. I guess it could be similar to a brushless motor turned generator

Tzarnal posted:Your local tire place has a machine that will spin a tire and then tell them exactly what weights to put where to make it balance out. This is ofcourse much more complex, lower tolerances and highly catastrophic should it fail but the art of balancing a big spinny thing is old and well explored.

Agreed in all cases. The warning was enough for me, so thanks, but we try to keep snuff and corpses out of osha even though it's heavily implied they existed and justified a rule and silly training video. But how does this happen? Some folks got caught under a press that gets generated from too many people willingly filling a place with no outflow options? It looks like there were even fences in some places? Seems like they're would be more outlets for a high density flow, but maybe that's a Seoul geography thing.

It also helps to use the [ code] brackets. It allows to post links that aren’t clickable unless you put in effort to copy/paste the link. code:

Yeah if it's clearly labeled and described and you click it without reading that's on you, but I understand people not wanting clearly dead/dying people posted in this thread. That said, gently caress crowds. We weren't meant to be with so many in such a small area and it triggers every loving flight instinct I have even to be in a crowded venue for a concert or whatever.

social gatherings are good for your mental health and soul. just be aware of where you're at in the crowd and where the exits are. drat lol

Yeah...the crowd seems to be full of young people, who I guess are more likely to be outside on Halloween, but it struck me as a general lack of awareness of the danger. I'm not sure if the areas have had to deal with surges before, but you can imagine times squares new years festival in contrast. But honestly you can't always know if you're a part of a press, or about to be. Trampling is not a thing you blame on one person. It seems like an infrastructure failure, which makes it threadworthy.

I've been in huge crowds at festivals and sports events before and although there's always this looming danger, it's been fine... so far. No idea if you can even do anything if things start to go bad.

All it takes is one person to stop, or trip, or fall, or get stuck on something, and you can start a crush. People keep moving forward because they don’t know what’s ahead. By the time they meet the crush, they are being crushed themselves. I remember the “Battle of the Bastards” episode of GOT and that crush was just… gah. Didn’t matter if it was fictional. It was really, really hard to watch. Hillsborough. The Station fire. The Hajj, multiple times. Astroworld. Narrow paths, kettling, and panic. Always know where your exits are and keep calm.
