Basic Definitions (Recap)
Stress Intensity of internal reaction forces per unit area.
Normal Stress: Cause by the force
applied perpendicular to the surface.
Shear Stress: Cause by the force applied
parallel/tangential to the surface

Mechanics and Continuum Mechanics 
Mechanics is the branch of physics that studies the behavior of a body when it is
subjected to forces, (e.g. deformation) and how it evolves over time.
Theoretical Mechanics establishes the laws that govern a particul
