It all depends on the part and why it was rejected....some simply get rejected and scrapped, where others can be fixed and reintroduced on the line. Each station on the line keeps track of EACH part in the progression and can again reject the part (or assembly) at any given time. It can never be forced through production.

Now that we have global suppliers, each and every part is barcoded so if a part/assembly in Mexico get rejected that is intended for another assembly in the US then production might be halted until the process is fixed. All the lines are managed by a central database and can track quality in real time. This data then is incorporated in the warranty department so if there are a lot of warranty issues coming in once the vehicles are on the road we can literally track WHY it failed and then work to fix those issues. To prove this, you may get a recall on a vehicle and in that notice it will say 'recall for vehicles built during X time'....your recall will fix the problem they already found and fixed/updated in the assembly line

This is usually my experince with it. Usually I am also experiencing a sort of mental fuge state at the same time.

I modified a pen torch to work with a valve stem and mounted one of those to the chamber. Of course, I only used the oxygen cylinder of the torch.

I like your solution. Can you post a picture?

Must’ve take a lot skill to do things correctl, but what happens to the workers that get it wrong?

It's more accurate to say that fire is the chemical reaction than it is to say that fire needs a chemical reaction.

So op got it right. It could be either depending on if some has digested or not.

Unless you're actually thinking of rumination. ;)

That’s interesting thank you, but what happens to the rejected parts? Does it get recycled?

Because "simple" isn't always the same as "short." Even if you're not addressing the actual complexity of the answer (see Rule 4), breaking a complex concept down to where it's understandable is often not a short process.

Complex concepts are condensed things that often contain layers of foundational understanding, which then have to be unpacked for a layman to grasp the concept.

>Unless OP states otherwise, assume no knowledge beyond a typical secondary education program. Avoid unexplained technical terms. Don't condescend; "like I'm five" is a figure of speech meaning "keep it clear and simple."

Well lil guy, sometimes people can really really really like the question. They like it so much that they have a whole lot to say. It's a normal thing for people to get excited. I bet you get excited over...trucks? Candy? Ball games?

It's like that but they want someone else to really understand. Sometimes we know so much about something that it makes it hard to explain to others l. So there really is only one way. Sometimes there are not smaller words for the big words.

What I do know is that at the end of the day, the person who asked the question ends up being happy with some sort of reply.

Now who wants to go to the park?

>LI5 means friendly, simplified and layperson-accessible explanations - not responses aimed at literal five-year-olds.

-Sidebar

If we literally answered like people were five, it'd be way less helpful and probably fairly condescending. If a question isn't quite clear enough, nobody (well, most) won't be offended if you ask for more clarity.

The rules for this subreddit are that we are not literally explaining things to 5-year-olds. "Explain like I'm five" is an expression that means "please explain this simply to me."

There are other subreddits that are literally about giving explanations on a 5-year-old level. But this one's rules are that we are writing for the adults who are actually using Reddit. Not for a theoretical child.

Also, many of the things that people ask here aren't very easily summarized on a child-friendly level.

Who told you eating fast food is linked to mental health problems?

Might be a good time to reevaluate where you get your info.

I am in the automation business. The assembly lines are automated to create each item repetitively and within very tight tolerances. Its actually rare that items (here in the US) are 'hand built'. The machines are intelligent enough to reject any part during any process so that the bad parts/assemblies don't make it to market. An assembly line can assemble a V8 engine every 70 seconds with less then 10 people on that line.

That's again very likely a deja vu, your brain just mapped your real world to a memory of a dream.

Repetition and specialization.

Instead of having a team of 20 dudes building a plane from start to finish, two guys will rapidly and previcely do the first approximately ten percent, then another team will do a little work, then another team, and another, and another, with each team specializing in getting really really good at only the part of the process they're involved in

>As if the US does not have deserts

He addresses that, too. We have deserts, but we don't live in them. Compare this map if the North American deserts

with this map of population density

...well, actually, we do, sometimes. Las Vegas, Phoenix, Tucson, Albuquerque, Santa Fe, Salt Lake City, etc. Thing is, the people who live there have the technology and money to.. well, live there.

>and as if Afracia does not have jungles.

He specifically mentions areas with 'sand', and where food can't grow. Sheesh.
