Problem 419
Use the method of sections to determine the force in members BD, CD, and CE of the Warren truss described in Problem 408.
 

Problem 418
The Warren truss loaded as shown in Fig. P-418 is supported by a roller at C and a hinge at G. By the method of sections, compute the force in the members BC, DF, and CE.
 

Problem 417
Using the method of sections, determine the force in members BD, CD, and CE of the roof truss shown in Fig. P-417.
 

Problem 414
Determine the force in members AB, BD, and CD of the truss shown in Fig. P-414. Also solve for the force on members FH, DF, and DG.
 

Problem 412
Compute the force in each member of the truss shown in Fig. P-412. If the loads at B and D are shifted vertically downward to add to the loads at C and E, would there be any change in the reactions? Which members, if any, would undergo a change in internal force?
 

Problem 411
Determine the force in members AB, AC, BD, CD, and CE of the cantilever truss shown in Fig. P-411. If the loads were applied at C and E instead of at B, specify which members would have their internal force changed.
 

Problem 410
Determine the force in each member of the Pratt roof truss shown in Fig. P-410.
 

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

Problem 408
Compute the force in each member of the Warren truss shown in Fig. P-408.
