ng frame. The derivation of these equations will now be given. M=M.+m (FK-4) Figure 7 sbows part of a wing frame consisting of equation (FK—3) may be transformed to two parallel spars connected by a number of ribs. The ribs are numbered, beginning with zero at the wing tip, TF+TB+b^=0 (FK-5) and… … Fioube 7.—Free-body diagram of wing frame with many ribs. stations, the relation between the torques TF and TB is board of the nth rib. The forces acting on the face given by of each cut are a shearing force S, a bending moment M, and a torsional moment T. The external load consists of a running…
