What's the thought process for these people? Winning in the court of public opinion is nice, I guess, but that's not the court that will decide whether you're guilty of negligent homicide.

Safety factors are an important part of design work. For life-threatening failures, they tend towards 6. That means you list a 100 lb limit, and build it to take 600 lbs.

Honestly, sounds more accurate than what I wrote. +10% is so small of a number, holding a little thing in a small clamp with no danger would still be at least +50%, even just to allow the system to lose strength if it wasn't taken care of over time (ie, used in a factory where maintenance = lose of money).

Edit: I don't work on things that can kill people, to be clear! I'm not an expert on that.

Part of engineering is working within your constraints. Non-critical parts might end up less cost effective than a maintenance swap if you design them to last forever in an application that really doesn't need to last forever (because an accident or environmental wear will put them out of action before fatigue does.)

On the other hand, elevators have a safety factor of 11, and I don't trust all of them.

So it's kind of weird that we got two videos in about a week of a front loading concrete hauler that had to stop short and dump over idiots in traffic. Not that I'm complaining, just interesting is all.

What is the car even hitting here? Giant snare trap? EDIT: 5th watch finally get it. Looks like a guy-wire

Back to my age old question - why are you recording what should be something mundane? Unless pulling into the drive in obnoxious way is just what he does.

Specifically, it's hitting the screw-in anchor that the down guy attaches to. Those are at least six feet deep and are rated to 10000lbs of guy tension on the small end, so they're absolutely going to win an argument with any consumer vehicle.

It's supposed to be his employer's responsibility to ensure a safe working environment and provide appropriate PPE, but unfortunately it's fairly common for welders to be ignored so they can just get the job done. Especially if they're working plant shutdowns and outages.

If feasible, local or area ventilation is an ok option to help remove the fumes and/or toxic gases. The next option is for the employee to wear a respirator. There are several types and probably the easiest way to break them down is into non-powered versus powered. Under non-powered, you have disposable half face (like the N95), reusable half face, and reusable full face. These are basically powered by your lungs. You're inhaling air that is being pulled through a filter. They are not comfortable to wear.

When it comes to powered, there is only a full face style and a hood style. These have a device that hangs off the back of your belt. The device has a fan that pulls air through a filter and then shoots it up a tube that runs up your back and connects to the back/top of the mask/hood. The clean air is then blown in front of your face. On a previous project, I had several welders that needed to use these so they could weld on stainless steel pipe. They are holy poo poo expensive. Like $1500-$3000 each. My guys loved them. They said the air getting blown on to them was cool so they stayed pretty comfortable.

There are also a bunch of different filters depending on what the hazard is (particulate, organic vapor, acid gas, etc).

Really it depends on what type of welding your cousin does, what sort of material he works with, what sort of environment he is in, and how much welding he actually does each day. There are a bunch of factors that go in to choosing a respirator so it's not really for me to say he should be using one versus another. If he has a company or plant safety representative (or better yet an industrial hygienist), they would be the one to help him make that determination.

This doesn't even get in to all of the different requirements that would be expected of his company if he did need to wear a respirator.

Powered air hoods are absolutely the current standard and if it is possible for them to be used, they should be used. They even have auto-darkening faceplates built in.

The short answer to whether current or near-future computers can drive a car at the human or near-human level is no.

The long answer is, we don't even know how human brains work, let alone how to make an AI that can drive a car. Computers are good at solving strictly bounded problem sets, and safe driving is the opposite of that. Not to mention that the work is being done by a bunch of techbros who don't even ask the right questions.

Will wasabi powder burn? I think the principle is that anything that's both combustible and finely grained enough to become airborne can cause an explosion, it's a physical process not a chemical one



vvvvvv I mean, it doesn't depend on what the powder actually is, just whether it ticks the boxes

Yes, any remotely combustible powder is a fire hazard, an explosive hazard, and likely a breathing hazard. The finer the powder, the worse it is.

Yeah, these coil guns are fairly lovely. Projectiles are not rifled so they are innaccurate, and come out pretty slowly. You got to start somewhere but I'm not sure where the tech will go. I assume we need better power storage and delivery to give it a lot more oomph.

The simple fact that the chemical energy density of current gen propellants is so far beyond what we can get out of even the best capacitors, let alone batteries, makes electrical weapons a dead end -- and that's before you look at cost. Smokeless powder is cheap.

So are you all going to have to dig up a bunch of buried lines? Because to this armchair idiot who knows nothing about electron fuckling "we saw smoke coming from the ground over buried lines" sounds no bueno niet goed

It depends on whether they can use directional boring to replace the lines. I doubt transmission size stuff can be done without daylighting it.

They can't pull a new cable through the same conduit?

Not if the conduit is damaged, it might tear up the insulation. For a distribution conduit you just pull the old cable out and blast the borehead through whatever conduit is already there, and it pulls the new conduit behind it, but there's an upper size limit on directional boring machines.

They'll probably run an optical check through the conduit after they pull the old cable to see if they can re-use it.

e: And this is assuming that the transmission line was pulled through conduit, some of this stuff is so big that is has to be laid and then a shell built around it.
