Hey Matt,

Tom Senior hit the key point about the contribution of thrust in
developing lift; engineers love to argue this point. I have this
series of videos and lessons from NASA, two of which I have used in a
class discussion about lift and drag:

You may download the PDFs for all lessons for free, as you already
paid for it in taxes. These are good videos to pique student interest
especially those who like aerospace topics. If you listen closely the
test pilot says a few wrong things, another website had a list of a
few more errors, but in general the drag and lift discussions show how
common engineering applications involve multiple calculations from
physics.

Howdy all,

Got a question for the list. If I wanted to calculate the lift force
on an airplane wing, how would I do it? I know it basically boils
down to F=PA, where P can be determined from the Bernoulli effect.
However, in Bernoulli's equation, how do you determine the speed of
the air moving over the top of the wing as compared to the air moving
beneath the wing? This is my point of confusion.

Thanks in advance, and I hope everyone has a Happy Torquey Day :)
