Avit 323 Block 9 Exam: Lift Equation
Questions & Answers 100% Accurate!!
Lift Equation - ANSWERSLift=CL((ov2)/295)S

Coefficient of Lift - ANSWERSthe ratio between dynamic pressure and lift pressure;
measures efficiency of the airfoil generating lift

rectangular and elliptical wings - ANSWERSstall at root first

tapered wing - ANSWERSstalls at trailing center first

stagnation point - ANSWERSa point in a flow field where the local velocity of the fluid is
zero
laminar flow - ANSWERS-seperates earlier
-more pressure drag
-less viscous drag

turbulent flow - ANSWERS-seperates later
-less pressure drag
-more viscous drag
Where can you find the wing surface area? - ANSWERSPOH Section 1
Archer: 172 sq. ft.

Cl(max) - ANSWERSthe angle of attack where any increase in AOA will result in
decreased lift (stall)
