Welcome to the discussion of US Politics!

Rules:

  1. Post only links to articles. Title must fairly describe link contents. If your title differs from the site’s, it should only be to add context or be more descriptive. Do not post entire articles in the body or in the comments.

Links must be to the original source, not an aggregator like Google Amp, MSN, or Yahoo.

Example:

  1. Articles must be relevant to US politics and contain quality and original content. Social Media adjacent hosts like Substack are allowed, but ONLY if they tie back to a company/subsidiary. No personal or friend group blogs and no self-promotion. Articles should be worth reading. Clickbait, stub articles, and re-hosted or stolen content are not allowed. Check your source for Reliability and Bias here.
  2. Be civil, No violations of TOS. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing other users of being bots or paid actors.
  3. No memes, trolling, misinformation, or low-effort posts/comments (including reposts). If you see posts like this that anger you, do not engage. Report, block, and live a happier life than they do. Any slap-fight is subject to comment removals. Fights full of rule violations will result in temporary bans to cool off.
  4. No manipulating votes via bots or alt accounts; this will result in permanent bans. Vote based on comment quality, not agreement. This community aims to foster discussion; please reward people for putting effort into articulating their viewpoint, even if you disagree with it.
  5. No hate speech, slurs, celebrating death, advocating violence, or abusive language. This will result in an account ban. Usernames containing racist, or inappropriate slurs will be permanently banned.

We ask that the users report any comment or post that violate the rules and use critical thinking when reading, posting, and commenting. Users that repeatedly have comments or posts removed, weaponize reports, or violate the code of conduct, will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users. The reason(s) behind moderator action(s) are publicly available through the Modlog.

That's all the rules!

Isn't there some question about the specifics of the mechanism of lift itself? Not like "this shouldn't be possible!" but more "it's easier to explain than it is to understand"

[–] kryptonianCodeMonkey@lemmy.world 36 points 10 months ago (1 children)

No, the science and engineering is well understood and can be calculated entirely in models that use this knowledge to precisely predict thinks like lift and drag. There is no guess work or mystery about it.

However the common "facts" that we are often taught as explanation to children and the layperson for lift are wrong and/or incomplete. The Equal Transit Theory, i.e. the idea that when a wing splits the air, the air above and below must meet at the same time on the back of the wing causing the air on top to have to move faster due to the greater distance to travel, is just not true.

However that lower pressure above the wing that doesnt actually result from the Equal Transit Theory, that part is true. It is caused by the deflection of air on the underside of the wing causing the higher pressure underneath and lower pressure over the top. Lower pressure over the wing does in fact cause a component of lift due to Bernoulli's Principle. But it is also not the entirety of the source of lift. Other components include the Coanda Effect from the curvature of the wing redirecting air downward, as well as the just simple propulsion caused by the propeller(s)or jet(s) and downward deflection of air hitting the underside of the wing, which is basic Newtonian motion (3rd law).

Huh, okay. I don't really keep up with all of the little fandoms, so thanks for that!
