Zero-Force Members & Truss Design Intuition
Inside this lesson
- Apply Rule 1 (two non-collinear members, no load) to flag both as zero
- Apply Rule 2 (three members, two collinear, no load) to flag the third as zero
- Cascade the rules: use a newly-found zero to unlock the next
- Explain why zero-force members exist in real structures despite carrying no design load
