Question
3 - The ratio of the lift force ( L) to the drag
force ( D) for the simple airfoil
is
(L/D = 10 ) . If the left force on a short
section of the airfoil is ( 50N), Compute
the magnitude of the resultant force ( R)
and the angle (0 ) which it makes with the
horizontal.
Air flow
Ans. R = 50.2 N ,0 = 84.3°
