Homework Statement
Determine the zero force members in the following truss
Homework 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.
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!
