Howe truss

In Figure P-420, assume that counter diagonals act from B to E and from E to F in addition to the counter diagonals CD and DG shown in the figure. Assuming that these counter diagonals can support tension only, determine which diagonals are acting and the force in each.
 

Problem 428
Use the method of sections to determine the force in members DF, FG, and GI of the triangular Howe truss shown in Fig. P-428.
 

Problem 423
Use the method of sections to determine the force acting in members DF, EF, and EG of the Howe truss described in Problem 409.
 

Problem 420
Determine the force in members DF, DG, and EG of the Howe truss shown in Fig. P-420.
 

Problem 409
Determine the force in members AB, BD, BE, and DE of the Howe roof truss shown in Fig. P-409.
 

Problem 267
The Howe roof truss shown in Fig. P-267 carries the given loads. The wind loads are perpendicular to the inclined members. Determine the magnitude of the resultant, its inclination with the horizontal, and where it intersects AB.
