Problem $5$

A flat, thin, rectangular wing with constant chord c and span b is to have elliptic

loading at design condition.

$\backslash$Gamma $=\backslash$Gamma $\_(0)\backslash$sqrt$(1-(($y$)/(($b$)/(2)))^(2))\backslash$Gamma $\_(0)$ b and c$.$

ii$.$ What are the twists at the root $($y$=0)$ and the tip $($y$=($b$)/(2))$c stays constantc$\_($l$)$ versus $\backslash$alpha is linear until the stall angle $\backslash$alpha $\_($s$),$ and the incidence of the wing is

progressively increased, will it stall first at the root or the tip? What if the wing

were elliptic in planform and untwisted?
