does anyone have hard statistics on whether unionized workplaces have more or less accidents/safety violations than non-unionized? anecdotal experience is also welcome im also curious about statistics with workplace safety in regards to cooperatively run businesses. im looking to see if mondragon has any documentation online but i cant find any

KoRMaK posted:this shits hilarious, gently caress Elon musk, but I hope SpaceX does well. Second shot is beautiful Speaking of rockets, I love this hour long episode about a tour of a modern rocket factory. My favorite part was how the CEO explained why they were manufacturing rocket hulls using orthogrids instead of the older isogrids. He explains why they prefer orthogrids because they are lighter, stronger, and much, much easier to machine. Some wizards in the 60's punched in a question for a computer without stopping to think about how assembly performs logic. The primitive series of BJT transistors gave them the answer known as the isogrid rocket hull. Decades of rocket scientists never bothered to math why this was supposedly the mathematically ideal rocket hull design. The isogrid was not an ideal rocket hull design.  Here's an isogrid by the way. Triangles, laughable.  Orthogrid. Literally just squares, that's it.

Then again, given that these places are operating 24/7 on 4x4 12-hour shifts, I suspect that the bosses may have come together and realised that actually protecting/training their staff impacts the bottom line less than having to draft in replacements on short notice. Enlightened self-interest can be put to good use!

This is a really inaccurate post. Like...you got basically every fact wrong. Including what’s said in the video. The isogrid design is stated in the video to be from the 90s not the 60s and that part about ??”BJT transistor generated isogrids”?? is dumb bullshit you made up. Also while I can’t claim that those parts are identically complicated to machine without seeing a print, a rectangular pocket and a triangular pocket are more-or-less identically complicated for a CNC machine. Also those aren’t squares. The idea that probably a hundred stress engineers, all of them trained in how finite elements work from the the classes where you calculate the matrices by hand up through using the software, never thought to consider anisotropic designs is just insulting. Way to make the world dumber. CarForumPoster fucked around with this message at 12:24 on Dec 12, 2020 |

Platystemon posted:The cyclist in the video has weak arm extension, but signalling a right turn with the right arm extended is allowed. That poo poo there is hurting my head. Im guessing this is the officially correct use of handsigns in the USA? Cause it sure as poo poo isn't correct in Denmark. (Yes I did have to go look it up, thanks for making me doubt what i've known for the last 30 years) In Denmark you: Extend your left hand to the left when indicating a left turn. Extend your right hand to the right when indicating a right turn. Raise your left hand when indicating a stop. Thats it. Goddamn I'd be stressed out trying to work out what the gently caress you guys are trying to if I ever went to the US and tried to get anywhere on a bike or in a car.

Literally the only difference from what you described is the extra option in the middle and as previously mentioned that’s necessary to keep your right hand on the throttle/front brake of a motorcycle. Also for an unsignaled car. When turning right in an unsignaled antique vehicle, do you reach your right hand out the right window?

SerthVarnee posted:That poo poo there is hurting my head. Im guessing this is the officially correct use of handsigns in the USA? It's the same signals used for both bike and car. You stick your left hand out the window in a car, which is why that's used for all signals. You're tested on this when you get your license (at least I was in my state) but I know no one except cyclists remember the correct right hand signal, but it's the lawful way.

This. It's the sort of thing that any engineer will do as part of their coursework. My education was biologically inclined, so I did my stress work on bones, calculating which vertebrae would be most affected by the action of picking something up in different conditions. Also, calculating the strength of a design like that is relatively trivial as far as FEA goes. It gets even more laughable when you realize that recently, the advent of 3D printing and additive manufacturing has lead aerospace to consider making parts in a completely different way, and the idea that aerospace engineers would only think about the aero part of their education and not the space part of their education is very silly.

I got no problem with using those signals a you describe on a motorbike or in a car. That makes sense do to the physical restrictions of the vehicles. I'm having problems with the bicycle signalling. Where the Danish sign for stop is used as an american alternate sign for right turn.

FuturePastNow posted:you don't want to ride a bike in the US I agree entirely, but thats a seperate matter. Its just one of those things that make your head protest aggressively because of the unexpected loss of faith in standardized rules. Like the fact that Swedish trains still drive on the left side of a double track where Danish ones drive on the right side. It fucks up your ingrained knowledge and makes you spend a couple extra seconds trying to figure out something ridiculously simple.

Every cyclist I know (in the US) just points in the direction they're going and the low open palmed "whoa, hold up" gesture is universally understood to mean stop. It's the sort of gesture you'd make to stop your buddy from stepping in dog poo poo on the sidewalk. Everyone gets it. But this poo poo is bananas:

[...] Also, calculating the strength of a design like that is relatively trivial as far as FEA goes. Yea this is why I got so bitchy about it. It denigrates a profession that takes weight and safety very seriously and which directly affects every person who drives a car or flies on a plane. I took two classes in this as a junior in mechanical engineering. Every engineer understand the differences in simulating those two designs and why it was a challenge/constraint in the 90s but not in 2020. The guys and gals in the stress group I worked with at [big defense cos] often had masters degrees or PhDs focused in this area and that was on a mil airplane that’s been flying a long time. The foundational stress experts that make “we’re going with an isotropic design” do so after significant trade studies, prototype building, and real world testing and will easily have 20+ years experience and a PhD.

I went from a large 8,000+ worker construction project that was non-union to another 8,000+ worker project that was union. The number of incidents was roughly the same at both places. Around 10-15 incidents per day Monday through Friday (less on the weekends) and 1-3 OSHA recordable incidents each week.

Yes, I'm thinking about it and while it won't catch you unawares and is basically a big spike on the ground you have to fall onto, if you do it will cheerfully pull its way through you. Still safer than a lot of other homemade things though.

IIRC the last time the thread did a tour of homebrew wood splitting devices it was a majority view that the coil-spring rocking type was the least likely to horribly maim you. https://www.youtube.com/watch?v=R3VMhfIsfm0 other advantages: no electrical power required for use, can be made of recycled materials, not technically complex to build. if you really wanted to go nuts with safety you could probably install a two-hands-required brake mechanism, so you can't place your hand under the cutting edge while operating it.

Still safer than a lot of other homemade things though. I'm trying to imagine what it would be like. Unless you really impaled yourself on the bit with force, I don't think it would do all that much on you except ugly bruising, like it wouldn't bite into you like it does with wood. But your clothes would probably get entangled and you would be dragged into it. So better operate it naked. like ur mum

I like the kinetic log splitter type. https://www.youtube.com/watch?v=A1AqMZavQM8&t=29s Small motor, big flywheel, pull the lever to engage the rack with the pinion and use that momentum to drive the log into a stationary wedge. This example needs guards on the flywheels and belt and a two‐hand interlock, which commercial units do have. https://www.youtube.com/watch?v=WT_ympItuok
