What is Physical compression?
'''Physical compression''' means that a material under [[compressive stress]] reduces its [[volume]]. There are different uses of compression in [[physics]] and [[engineering]]. By compression it is possible to measure mechanical properties of materials such as [[compressive strength]] or [[modulus of elasticity]]. [[Scientist|Scientists]] do this with press machines. When gases are compressed, their volume becomes smaller as seen in the [[Ideal gas law]]. This compression is used in gas [[engine]]s, for example in the [[Diesel engine]] as in any [[internal combustion engine]] and in the [[steam engine]]. ==Related pages== * [[Strength of materials]] * [[Compression member]] * [[Tension (mechanics)]] {{physics-stub}} [[Category:Mechanics]]
