A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

It's crazy that a 60 ton metal airplane can just fly (lemmy.world)

I flew for the first time on a plane last week and I've seen planes take off at the airport. It looks crazy. But being on one is totally different like holy shit. The thing just FLIES. It just.... Soars... Through the sky! Like whoa man. Wtf... It's crazy. With how much these things weigh, it's insane to me the thing can just go up and bam, there we are, we're flying now. Like wow... Dude crazy.

Its all in those powerful engines

Not really. The thrust those engines produce is only about 1/3 the weight of the aircraft. It's in part thanks to the engines for sure though.

You make it sound like 1/3 is a small number. That's enough to accelerate the plane quickly and the speed is what generates lift.

I just meant that thrust is only 1/3rd the equation. The rest is the wings that convert thrust into lift at 3 to 1 ratio. And then there is all the systems that keep it controllable and safe etc.... it's a miracle machine really....

A few jobs back I was working was on a little learjet that had a .75 thirst to weight ratio. Now that was a fun jet. Now I have 54k lbs if thrust in a plane that weighs anywhere from 100-160k lbs.
