Calculate the forces in members BE and BD of the loaded truss. The forces are positive if in tension, negative if in compression. Assume F = 4.4 kN, a = 2.3 m, b = 3 m, c = 2 m, and d = 2 m.
In order to find BE we will resolve force at point E
Force in member BE = 0
In order to find force in BD, we can resolve force along a vertical direction at point B
Now we need to find FAB
At point A resolving along the vertical direction
Substituting in equation 1
