A fundamental force in physics and engineering where matter is subjected to pushing forces that decrease volume or length, critical in structural design and natural systems.

Compression

Compression represents one of the most fundamental forces in both natural and engineered systems, playing a crucial role in everything from structural engineering to molecular bonds.

Physical Principles

Basic Mechanics

Force application causing reduction in volume or length
Opposed by internal material resistance
Related to stress and strain relationships
Governed by Hooke's Law in elastic region

Types of Compression

Axial Compression
- Direct force along central axis
- Common in columns and pillars
- Critical in buckling considerations
Volumetric Compression
- Uniform pressure from all directions
- Important in fluid dynamics
- Relevant to material phase changes
