The wing planform area (S) is shaded as shown. The wing taper ratio can be calculated as the ratio of tip chord to root chord, The mean aerodynamic chord can be found by integrating the individual section chords across the span. For wings with simple linear taper, the mean aerodynamic chord will roughly equal the mean geometric chord, measured relative to the leading edge of the wing’s Mean Aerodynamic Chord, or MAC, which is the root-mean-square average chord. For most wings this is very nearly equal to the simple-average chord c. The ℓh and ℓv tail moment arms are the distances between the Center of Gravity (CG) and the average quarter-chord locations of the ... The Mean Aerodynamic Chord has a chord length and a fore and aft position.

The mean aerodynamic chord of any wing is defined by reference I as, "The chord of an imaginary airfoil which would have force vectors throughout the flight range identical with those of the actual wing or wings." The mean aerodynamic chord is required in order that the designer may have a ready means for evaluat-ing the wing moments.

The pitching moment of a wing is nondimensionalized by the use of the mean aerodynamic chord C. Both the m.a. center and the m.a. chord lie in the plane of symmetry of the wing. However, in determining them it is convenient to work with the half-wing. These quantities are defined by (see Fig. C.1)'.Motor oils come in different weights or grades, and one of the most common for consumer vehicles is 10W-40.
