Consider an elliptical wing with a certain Aspect Ratio (AR). The wing has a profile with constant Ca over a range of angles of attack, where lift scales linearly. Express the C, value at which the wing lift to drag (L/D) ratio becomes maximum as a function of the wing AR and profile C, value. If AR = 10 and Ca = 0.006, find the values of C,, C, and L/D when L/D is maximum.
