Thanks for the reply Wsimp and Marc. I tried another approach. Since the shape of my wing is ellipse i used the formula for finding the centroid of half ellipse. I projected it vertically and that is the MAC i used. But i think I will also try that equation you gave me to check if my approach is legit. THanks.
