Problem 437
The center panel of the truss in Figure P-437 contains two flexible cables. What load P will cause a compressive force of 20 kN in BD? Then determine which tension diagonal BE or CD is acting and the force in it.
 

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 435
For the transmission tower shown in Fig. P-435, determine the force in member CJ.
 

Problem 434
Compute the force in bars GI, GH, EH, and HI for the scissors truss shown in Fig. P-433.
 

Problem 433
Compute the forces in bars AB, AC, DF, and DE of the scissors truss shown in Fig. P433.
 

Problem 432
Use the method of sections to compute the force in members AB, AD, BC, and BD of the truss shown in Fig. P-432.
 

Problem 431
Determine the force in the members DF, DG, and EG for the Parker truss shown in Fig. P-430.
 

Problem 430
The loads on the Parker truss shown in Fig. P-430, determine the forces in members BD, BE, CE, and DE.
 

Problem 429
For the cantilever truss shown in Fig. P-429, determine the forces in members DF, FH, FI, GI, and FG.
