Truss force analysis determines tension/compression in members using equilibrium equations. Essential for truss design and sizing.

- 1Apply method of joints or method of sections
- 2Use equilibrium: ΣF_x = 0, ΣF_y = 0 for each joint
- 3Results show axial forces in each member

أسئلة شائعة
What are typical truss force patterns?
Chords (top/bottom) carry primary loads; diagonals share shear; internal forces vary with geometry.
Why are trusses efficient?
All members primarily in axial tension/compression; minimal bending reduces weight needed.
