Also weird how giant steel tankers float on the ocean. Especially when they’re weighed down by all that cargo. It’s practically unbelievable. I throw a tiny rock in the ocean, and it sinks…but not those giant steel boats? /s

No, ocean water can’t sink steel boats
lostme@lemmy.world 3 weeks ago
It’s a well known fact that steel weighs the same as feathers
ByteJunk@lemmy.world 3 weeks ago
Well… When you put one of those huge tankers in the water, it will move a LOT of water out of the way.
As long as the tanker weights less than the weight of all that water it displaced, it will float.
As you keep loading up the tanker with more cargo, it will go deeper into the water right? But this means that it is pushing more water out of the way (the water that used to be where the boat now is), which balances out the weight because that creates more buoyancy.
A rock, on the other hand, is heavier than the water that it displaces, so it sinks like a tanker whose front fell off.

But steel is heavier than water
Saleh@feddit.org 3 weeks ago
Since we are pedantic, what you say isn’t true.
The tanker weights exactly as much as the weight of the water that it displaces. They are in balance. You describe it yourself. The tanker sinks deeper if it becomes heavier and swims more up as it becomes lighter.
The measure of “boat swims” is not the weight of the displaced water. It is weather there is some boat wall left sticking out of the water to keep more water from entering and displacing the air that keeps the submerged volume in weight balance with the water.
dwindling7373@feddit.it 3 weeks ago
Metal is heavier than water. Virtually every containber is fille to the brim with products, now I don’t know you but most everything we buy is heavier than water.
It’s clear they have some kind of extra propulsion in those, most likely magnetic anti gravitation.

But that’s only because of the spell that the ancient Wizard Archimedes cast in the elder days. Archimedes didn’t discover his principle, he molded reality to follow his rule.

It’s not pressure under the wings, it’s fucking Bernoulli sucking on top of them.
redhorsejacket@lemmy.world 3 weeks ago
When you nut, but Bernoulli keep sucking…
mojofrododojo@lemmy.world 3 weeks ago
I’m 100% convinced this was never a battle of airframes and manufacturers and simply was down to: “No, sir/ma’am, I will not fly the derpy plane into combat. Can’t do it. YOU DON’T UNDERSTAND THE REST OF THE PILOTS WILL LAUGH AT ME”
Salamand@lemmy.today 3 weeks ago
But then how can they fly upside down?
leftzero@lemmynsfw.com 3 weeks ago
Flaps. (As in, the hinged bits at the back edge of the wings, that essentially change the shape of the wing as required, not by flapping the wings; that’d be an ornithopter, as in Dune, not a plane.)
Psythik@lemm.ee 3 weeks ago

Rivalarrival@lemmy.today 3 weeks ago
The absolute maximum that Bernoulli can suck is 14.7PSI at sea level. Not even your mother can generate a greater vacuum.
There is no fundamental limit to the pressure that can be generated under the wing.
With sufficient thrust and proper angle of attack, a brick can produce sufficient pressure underneath it to generate lift.
leftzero@lemmynsfw.com 3 weeks ago
Fair enough, yet unless I’m mistaken most planes don’t rely on people throwing bricks at them (which would be quite risky anyway, for unless they throw them faster than escape velocity they’re bound to come back down eventually).

‘flying for no reason’

‘somehow joints don’t break’
Halfway might be overstating it
name_NULL111653@pawb.social 3 weeks ago
Nono they’re right about basically all but the no reason and ignoring gravity part. The fact that we can design an airframe that stays together under those kinds of forces is indeed absolutely crazy.

And they WOULD break, eventually, if they weren’t engineered to a statistically determined inspection interval and replaced/repaired at the determined overhaul time.

Thorry84@feddit.nl 3 weeks ago
Well I must admit, when the plane is resting on the ground, the wings droop down a lot. Then when airborne it’s the other way around, the wings curve upwards as the fuselage hangs from them. In my mind nothing that big made of metal should be able to flex that much.
But since I’m not a conspiracy theorist, I have learned about material science, airplane design and engineering. And I have found out that it does indeed flex that much. It also isn’t that thick, since it’s only a skeleton wrapped with a very thin layer of metal. In fact if it didn’t flex as much, it would be weaker and not stronger.
So the thing I really learnt is never to trust intuition when it comes to things like this.
taladar@sh.itjust.works 3 weeks ago

You can observe on a small scale that many things made of metal do, e.g. a saw or a spring.

It’s so rough watching all of those competent professionals at work, knowing that there are VERY few adults left in the room in what used to be the most important organizations on earth.
BastingChemina@slrpnk.net 3 weeks ago
Next time you see a plane imaging two hooks in the middle of the wings, a crane lifting up the plane with these two hooks and shaking it.
This give you a good approximation of what the forces in the plane are, and once you picture that you might think that there is no way the plane can hold up in this situation. Yet it does.
radix@lemmy.world 3 weeks ago
imsufferableninja@sh.itjust.works 3 weeks ago
It’s more like putting the plane in a bowl of jello and then shaking the bowl.
qjkxbmwvz@startrek.website 3 weeks ago
I think large planes “look” like they can’t work because their “relative speed” is really low — that is, their speed relative to their length. We’re used to seeing birds cover tens of lengths per second, whereas a large airliner covers ~1ish per second at takeoff.
Or not, but this always seemed like a plausible explanation as to why planes look impossible. (Though given that hovering birds don’t look funny, maybe this is a silly observation…).
SoleInvictus@lemmy.blahaj.zone 3 weeks ago
That’s a really thoughtful take, I’m glad you shared. I think it has merit. I think proximity is a factor too. The public rarely gets up close to a jet, but I can attest from personal experience they seem much faster when you’re closer during takeoff and landing.
Sylvartas@lemmy.dbzer0.com 3 weeks ago

Birds flying against the wind and staying in the same spot as a result do look kinda weird though. Especially if you are not aware/don’t notice there is mstrong winds
Ilovethebomb@lemm.ee 3 weeks ago
I remember a quote from an A380 pilot saying the plane doesn’t look like it should be able to fly.
Even the people that fly them know they don’t look like a flying object.
Chadus_Maximus@lemm.ee 3 weeks ago
I get it. The plane is so disgusting the earth tries to keep it away from itself.

Actually that’s something I don’t understand, they think the moon is a sphere about 100 miles across about 1000 miles above the flat Earth. Why couldn’t humans have flown that short distance?

Years ago there where a few sincere jokes with it now it is just straight up homophobia and culture war shit.
thebestaquaman@lemmy.world 3 weeks ago
I don’t know how you got to “culture war and homophobia”? It’s literally a meme phrase that’s used (often sarcastically) in response to stories on the internet. Saying something is “fake and gay” is literally shitposting, I think interpreting any deeper meaning into it is a bit of a stretch.
