3.21   Using stnip theory, determine the yawing moment developed by a flying
 wing having a rectangular planform and moving at a forward speed'of 75 m/s and
 a sideslip of 5 m/s at sea level. The wing loading is 2000 N/m2, aspect ratio is 8,
taper ratio is 0.7, sectional lift-curve slope is O.lO/deg, sectional drag coefficient
 CD.L = 0.015 + 0.0008a deg, dihedralis 5 deg, and wing span is 16 m. [Answer:
-1289 Nm.]
3.22     Plot the variation of (Cnp)A.W with angle of attack using the strip theory for
a swept-back wing with the following data: ALE  =  30deg, aspect ratio- 8.0,
span-Y16.0 m, taper ratio-l.0, sectional drag coefficient CDO.L - 0.013 +
