Subject to the aircraft wing by the average load is, so each site to calculate shear, moment and torque, we must first calculate its area in the plane and its force action line to the distance of a coordinate axis , and concentrated load line to the centerline distance. With a load equal to area multiplied by the average load, a shear force equal to this site before the site with loads of and all. Multiplied by the effect of shear force bending moment is equal to the corresponding axis line to the distance. Torque multiplied by the concentrated load is equal to the shear line to the centerline distance. The results results are consistent with written calculation. Program has some versatility.
