Wait til he sees the road design.

I have never thought about the fact that manhole covers need to hold up to weight. Of course they do and it's perfectly normal and sensible. It's just not a thought I've ever had.

[-] 9point6@lemmy.world 78 points 3 days ago

Technically it's the manhole covers that need to support the weight.

Manholes themselves are expected to do the opposite of holding weight

They hold light?

[-] boredtortoise@lemm.ee 35 points 3 days ago

It's dark inside so of course the light is held □

[-] WldFyre@lemm.ee 8 points 3 days ago

Structures underground experience buoyant forces that act to push them up. Manholes (and any structure bottom, like storm inlets, pump station wet wells, etc) need special consideration since they can be partially or mostly hollow, so they have to be heavy enough to remain in place.

[-] usualsuspect191@lemmy.ca 5 points 3 days ago

You know, I knew that but couldn't figure out what the opposite of weight was for some reason. Thanks for the extra learning!

Fun fact: Coffins experience this force too, and during flooding can rise up out of the ground

[-] superkret@feddit.org 2 points 3 days ago* (last edited 3 days ago)

Ah, that explains why my grandpa was buried in a lead coffin.
He lost a lot of weight right before he died, so he was too light!

[-] bnaur@lemmy.world 2 points 2 days ago* (last edited 2 days ago)

Right, so the light is actually pushed up by these buoyant forces and I guess that then also explains why it's so dark underground. Fascinating how learning some little new details about the world can sometimes make it all just click together!

But does that mean that light is actually hollow?

[-] Enkrod@feddit.org 2 points 20 hours ago

Well we know light is concentrated into comparatively tiny, but heavy points in the universe (stars), while dark fills the vast vacuum of space. So light in itself is likely denser than dark, ergo the light we have on earth must be forming hollow structures to remain lighter than dark when comparing by volume.

[-] grue@lemmy.world 3 points 2 days ago

Technically, the walls of the manholes, in turn, support the weight of the cover and whatever load is on top of it. The entire manhole is a weight-bearing structure.

[-] Whelks_chance@lemmy.world 20 points 3 days ago

For formula one races they weld them down to stop the cars incredible downforce from sucking them up into the air. Even then they sometimes get torn up and thrown around.

Very important to take them seriously.

[-] x00z@lemmy.world 5 points 3 days ago

Manhole covers are also a common exercise for engineering students. Like designing one that can hold x amount of weight with a specific set of limitations and/or requirements.

[-] Kerb@discuss.tchncs.de 134 points 3 days ago

literally unplayable

[-] Red_October@lemmy.world 107 points 3 days ago

Obviously in the dystopia of Night City, lighter weight manhole covers were approved for road use purely to cut costs, and any deformed or destroyed covers have the cost offloaded to the poor rube who last ran them over.

[-] RidderSport@feddit.org 82 points 3 days ago

So it is technically canon that cars start flipping or crashing for no apparent reason - the goddamn manhole covers broke.

[-] Klear@lemmy.world 9 points 3 days ago

Doesn't explain the driver still sitting in the smoldering ruin and laughing while on fire.

[-] knightmare1147@lemmy.world 21 points 3 days ago

Nah that's just the implants frying

[-] doggle@lemmy.dbzer0.com 36 points 2 days ago

I mean, I'd totally believe that night city isn't in compliance with their own manhole safety code

[-] MirthfulAlembic@lemmy.world 69 points 3 days ago

Most of the complaints about bugs in this game seemed overblown, but this is unforgivable.

[-] Kusimulkku@lemm.ee 8 points 3 days ago* (last edited 3 days ago)

You should've tried it on PS4 at release. It was glorious. I did have a ton of fun because of the bugs (couldn't progress in the game much) but if I had paid for it I would've been pissed

[-] TriflingToad@lemmy.world 35 points 2 days ago

this is like people on r/DeepRockGalactic complaining about the smallest things

[-] Gestrid@lemmy.ca 20 points 2 days ago

To be fair, double spaced where there isn't supposed to be one is really noticeable.

[-] zipzoopaboop@lemmynsfw.com 9 points 2 days ago

I feel the same about misalignment

[-] RamblingPanda@lemmynsfw.com 59 points 3 days ago

This is part of the test you need to ace if you want to get German citizenship. We have some standards

[-] Opisek@lemmy.world 11 points 2 days ago

We, in fact, have many DIN standards.

[-] BenLeMan@lemmy.world 5 points 2 days ago

And nowadays they are supplemented and partially superseded by European EN directives. This is the kind of stuff that hardly anyone realizes but is enormously helpful in everyday life. Your toilet seat breaks, you just go ahead and buy a new one. Its mount points, dimensions, and load bearing characteristics are standardized so no need to get a degree in toiletology or whatever. Just buy any one you like. Same idea with light bulbs, printer paper, piping connections, door jambs, etc. etc. Standardization makes life SO much easier.

[-] idiomaddict@lemmy.world 3 points 2 days ago

This is something I’ve noticed since living in Germany. I’m from the US, so I don’t know if it’s a metric:imperial thing or a German specific thing, but things are way more standardized here.

You’re not always allowed to fix your own appliances (or you can, but your insurance will be nullified for any even remotely related- like replacing the foot on a washing machine means that water damage from an unrelated leak in the washer’s drum years later may not be covered), so the standardization doesn’t always pay off, but it’s definitely standardized.

[-] Donebrach@lemmy.world 7 points 2 days ago
[-] zaphod@sopuli.xyz 42 points 3 days ago

It's not a bug, it's a feature, in this dystopian world nobody cares about manhole cover standards anymore.

[-] Akasazh@feddit.nl 9 points 2 days ago

You underestimate the Germans

[-] Enkrod@feddit.org 2 points 20 hours ago

This is what makes it a dystopia for us.

[-] justinbieber@lemmy.dbzer0.com 23 points 3 days ago

german humor, wonderful

[-] JoMiran@lemmy.ml 21 points 3 days ago

And then they fixed it, right? Right?!?

[-] jaybone@lemmy.world 13 points 2 days ago

These numbers don’t align though. 4271 is not a Bxxx or Dxxx and also isn’t on that diagram on the left. I’m so confused rn.

[-] 9blb@feddit.org 24 points 2 days ago

B and D are weight classes. B 125 is tested to 125 kN, D 400 is tested to 400 kN.

DIN 4271 tells you how manholes of class B are to be build.

[-] jaybone@lemmy.world 5 points 2 days ago

I see the number in the diagram now after looking more closely. Also seems the number is upside down in the game.

[-] Etterra@lemmy.world 3 points 2 days ago

Worst game ever -1,000,000 stars lol

[-] TaeKwonDoh@lemmy.world 6 points 2 days ago

What a nerd.

[-] AceQuorthon@lemmy.dbzer0.com 10 points 3 days ago

I unironically love germans

[-] CrowAirbrush@lemmy.world 4 points 2 days ago

But why's it say DIN 4271 tho?

[-] sushibowl@feddit.nl 8 points 2 days ago

DIN 4271 is the number of the standard that describes how to build manhole covers of type B125.

The correct manhole cover should probably state something like DIN 19584, which I think is the standard covering the B400 class manhole covers.

[-] CrowAirbrush@lemmy.world 1 points 1 day ago

Thanks for that, it confused me as it didn't line up with the story.

[-] weker01@sh.itjust.works 1 points 2 days ago* (last edited 2 days ago)

I've seen a manhole cover with din 4271 printed on it in Germany before. I've no skin in the manhole cover game tho

[-] scutiger@lemmy.world 1 points 2 days ago

According to this, it would make sense to see one on a sidewalk, but not on a road.

[-] huginn@feddit.it 5 points 3 days ago

Wintermute would complain about such mundanity.

[-] frezik@midwest.social 4 points 3 days ago

Rivet counters have come to video games, I see.

[-] jawa21@lemmy.sdf.org 2 points 2 days ago

You should look at the War Thunder forums....
