1. The problem statement, all variables and given/known data Determine the force in member BE of the loaded truss. See the attached picture. 2. Relevant equations Sum of the Moments = 0 Sum of the Forces = 0 3. The attempt at a solution Sum moments about A to get: -12L - 56L +40Dy = 0 Dy=1.7L Sum the forces in the y direction: Ay + Dy - L - 2L = 0 Ay = 1.3L Cut through BC, BE, and FE at "Q" Then sum the forces in the y direction: -BEsin(θ) + Ay - L = 0 BE=.3L/sin(θ) I'm really at a loss at how to get theta. The main problem I have is determining the horizontal distance between B and F. I am unable to determine what that distance is. If I had that distance I believe I could use the Law of sines and subsequently find theta.
