# Principles of Statics

**Statics** is a branch of mechanics which studies the effects and distribution of forces of rigid bodies which are and remain at rest. In this area of mechanics, the body in which forces are acting is assumed to be *rigid*. The deformation of *non-rigid* bodies is treated in Strength of Materials.

Topics in Statics:

- Resultant of Force System
- Equilibrium of Force System
- Analysis of Trusses
- Cables
- Friction
- Centroids and Centers of Mass
- Moments of Inertia
