literally unplayable

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 79 points 2 weeks ago (2 children)

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 36 points 2 weeks ago

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

[–] WldFyre@lemm.ee 8 points 2 weeks ago (2 children)

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 2 weeks ago (1 children)

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 2 weeks ago* (last edited 2 weeks 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 weeks ago* (last edited 2 weeks ago) (1 children)

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 2 weeks 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.

Gravity force is so strong even the candlelight can't esc- oh wait...

[–] grue@lemmy.world 3 points 2 weeks 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 2 weeks 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 2 weeks 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.

[–] Red_October@lemmy.world 105 points 2 weeks ago (1 children)

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 81 points 2 weeks ago (1 children)

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 2 weeks ago (1 children)

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

[–] knightmare1147@lemmy.world 20 points 2 weeks ago

Nah that's just the implants frying

[–] MirthfulAlembic@lemmy.world 65 points 2 weeks ago (1 children)

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

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

[–] zaphod@sopuli.xyz 42 points 2 weeks ago (1 children)

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 weeks ago (1 children)

You underestimate the Germans

[–] Enkrod@feddit.org 2 points 2 weeks ago

This is what makes it a dystopia for us.

[–] TriflingToad@lemmy.world 37 points 2 weeks ago (1 children)

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

[–] Gestrid@lemmy.ca 21 points 2 weeks ago

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

[–] doggle@lemmy.dbzer0.com 37 points 2 weeks ago

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

[–] justinbieber@lemmy.dbzer0.com 23 points 2 weeks ago

german humor, wonderful

[–] JoMiran@lemmy.ml 21 points 2 weeks ago

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

[–] jaybone@lemmy.world 13 points 2 weeks ago (1 children)

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 weeks ago (1 children)

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 weeks ago

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

[–] AceQuorthon@lemmy.dbzer0.com 10 points 2 weeks ago

I unironically love germans

What a nerd.

[–] huginn@feddit.it 5 points 2 weeks ago

Wintermute would complain about such mundanity.

[–] CrowAirbrush@lemmy.world 4 points 2 weeks ago (1 children)

But why's it say DIN 4271 tho?

[–] sushibowl@feddit.nl 8 points 2 weeks ago (2 children)

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 2 weeks ago

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

[–] weker01@sh.itjust.works 1 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

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 weeks ago

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

[–] frezik@midwest.social 4 points 2 weeks ago (1 children)

Rivet counters have come to video games, I see.

[–] jawa21@lemmy.sdf.org 2 points 2 weeks ago

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

[–] Etterra@lemmy.world 4 points 2 weeks ago

Worst game ever -1,000,000 stars lol

[–] Olhonestjim@lemmy.world 3 points 2 weeks ago

Wait til he sees the road design.

[–] SplashJackson@lemmy.ca 2 points 2 weeks ago

Uh, learned
