Talk:Lift force

Why Bernoulli should not be merged with Lift Force
Bernoulli's Principle is not the only cause of lift force, and is not even a particularly good explanation for the lift from airfoils. Any shape that displaces streamlines sideways relative to its direction of motion through a medium will generate a lift force, by simple reaction from the displacement of fluid along the bent streamlines. For example, while the magnus force generates lift that usually agrees in direction with the Bernoulli lift force using a whirlpool explanation (that is the explanation in the current article), in some parts of the speed/spin-rate trade space there is a reverse magnus force that acts in the opposite direction. (note the red -- one of these days I'll have to pen something. Meanwhile, check out the  now-ancient sci.physics faq pennned by a much earlier me.)

So, er, while some expansion and cross-referencing is needed, I think that the solution to the current similarity is to expand lift force rather than to tie it to bernoulli principle. zowie 18:30, 7 October 2005 (UTC)

Fluid Mechanics
If anything, this article should be merged with Fluid mechanics or Fluid dynamics. Bernoulli's equation is one of a basic equation of fluid dynamics, NOT lift force. Lift force itself is simply an application of fluid dynamics. Also, Bernoulli is used for so much more than lift force calculations. Bernoulli is also used in pump calculations, for example.
