In preliminary design studies, the vertical forces on an airplane’s wing are modeled as shown. The distributed load models aerodynamic forces and the force exerted by the wing’s weight. The 80-kN force at x = 4.4 m models the force exerted by the weight of the engine. Draw the shear force and bending moment diagrams tor the wing for 0<x<4.4 m.
