1. The problem statement, all variables and given/known data Determine the zero force members in the following truss 2. Relevant equations - If only two members meet in an unloaded joint, both are zero-force members. - If three members meet in an unloaded joint of which two are in a direct line with one another, then the third member is a zero-force member. - If two members meet in a loaded joint and the line of action of the load coincides with one of the members, the other member is a zero-force member. 3. The attempt at a solution Ok, I got 6 (there are 8 according to the solution) using the above rules: HF, HI, OQ, QR, BC, and DE The solution says that BE and LJ are also zero force members, but I have no clue why... Any help please? Thanks in advance!
