us, since the reaction at point A is known, the force in member AB can be computed.
Summing forces in the x-direction provides the force in member AC:
FFF
xACAB
=− =
0: cosθ 0
(2.42)
As shown, member AB is in compression and member AC is in tension. Moving to
joint C, the following free-body diagram can be drawn as in Figure 2.19.
Summing forces in the x- and y-directions yields the following relationships:
