Truss

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 427
Determine the force in bars BD, CD, and DE of the nacelle truss shown in Fig. P-427.
 

Problem 426
Using the method of sections, compute the force in bars FH, GH, and EK.
 

Problem 425
In the Fink truss shown in Fig. P-425, the web members BC and EF are perpendicular to the inclined members at their midpoints. Use the method of sections to determine the force in members DF, DE, and CE.
 

Problem 424
For the truss shown in Fig. P-424, determine the force in BF by the method of joints and then check this result using the method of sections. Hint: To apply the method of sections, first obtain the value of BE by inspection.
 

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 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?
