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 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.
