Engineering reference data for Truss Analysis — Method of Joints and Sections in statics.

Key Formulas

Equilibrium

$\sum F = 0, \quad \sum M = 0$

Sum of forces and moments equals zero for a body in equilibrium.

Stress

$\sigma = \frac{F}{A}$

Force per unit area.

Moment

$M = F \cdot d$

Force × perpendicular distance.

Variables
