That train has engines from 3 different companies leading. I wonder how much more of a pain in the rear end that made all the cleanup and insurance paperwork? Obviously only one company is going to be operating the train, but they're going to have borrowed the power from the other two companies, which has to make things more complicated.

Are trains required to always stop after an accident, or if they plow through a small enough vehicle does the conductor just keep on trucking?

Trains probably have to consider stopping distance and making sure none of their payload is blocking traffic the half mile back. I'm not sure if they are required to stop for any accident that doesn't impair functionality, or what benefit them doing so would have.

I'd guess they need to stop to ensure that debris from the accident isn't caught up under the train risking further damage to the engine and tracks and risking derailment.

Stack Machine posted:The camera being in sync with the rotation of the blade is mesmerizing. Makes me think strobe lighting rotating tools must be a terrible idea. So there's an old piece of equipment called a stroboscopic tachometer, that worked by cranking a numbered dial on a calibrated strobe light until a piece of rotating equipment looked stopped, then you look at the dial and that tells you how fast it's going. The problem is it's subject to "ghosting" and "doubling" the first is when you have strobe set at 1/2 the speed, and you see a ghostlike image every half turn, the second is when you set it to 2X the speed, and it looks normal because the rotor appears stationary, you're just seeing it once every 2 turns not every turn. The OSHA comes in when operators mistake ghosting for actual speed, and try to get the machine to turn faster by adjusting the governor more and more open, this leads to diesel engines and steam turbines exploding and sending hard metal bits at the workers. Unfortunately mechanical governors and stroboscopic tachometers have both been mostly rendered obsolete, so you don't get to see that much these days.

Yeah, that's like a timing light. Used for older cars to adjust engine timing, when distributors were still a thing.

I remember when you connected a light to your car's spark plugs and put a white dot on the timing belt, to try and get those things to agree.

I think they did it twice; first with a small boat which didn't support the myth, then later again with a medium sized fishing vessel where they said there might be something to it.

Huh. I was just thinking along the lines of "I'll just reach down and adjust the workpiece on this totally stopped lathe", but steam explosions sounds even worse!

All the way back at 2019, when I was working at a machine tool company, we lost a machine because the truck stalled out while crossing the traintracks. Total loss on a million dollar machine. That's why the freight companies have insurance! Stack Machine posted:The camera being in sync with the rotation of the blade is mesmerizing. Makes me think strobe lighting rotating tools must be a terrible idea. Here's a cool lathe video where they cut the part in half and used a strobe so you can actually see inside the part while it's cutting. Super cool concept (though not exactly fair for showing off tool performance since chip evacuation is so much easier with half the part missing.) https://www.youtube.com/watch?v=q2PP9P-p79w

haha holy poo poo no kidding I used those exact inserts at my last job and they made the longest stringiest loving pain in the rear end fishing line chips of my entire career and that was with through spindle coolant Interrupted cuts are hell on cutters though so props to the tool for surviving that demo

zedprime posted:Brown glass will stop some UV but it should be mentioned welding gives off an astounding amount and properly rated glass barely looks transparent so if you do enough welds through bottles while still focusing on the weld your eye's probably going to itch later tonight still. Auto-darkening welding helmets are always blocking UV. When they darken it's just a LCD screen going black to block the visible light.

Its not even 8am and ive learned something new today. Djing turntables have a series of dots around the rim and a pop up light to use in calibration, where at certain speeds the dots will appear stationary. Its the same concept but instead of a blinking light its the rotation of the rim that does the "blinking"

The strobe blinks at the frequency of your electricity, either 50 or 60 hz, to make sure the table moves at the right speed.
