Since,furthermore, no piece connects morethan two joints, each piece is a straight two-force piece, subjectedto a tensile or compressive stress along its axis, and any one maybe conceived to have a portion removed, when desired, in theisolation of the various * free bodies to be considered.… … Fig. 4a WEDGE—CANTILEVKK FRAME. 41 The free body in Fig. 49 enables us to find the stresses Eand F. Since only three forces are concerned,meetino^ at a point, a simple procedure is toresolve the known P into two components, Eand F^ along the action-lines of E and E^ asshown by dotted lines. E and E…
