The lubricants are defined as the chemical substances which reduce friction between two sliding/moving metal surfaces and thereby reduce wear and tear of machines .The lubricant keeps the two surfaces apart ,thus the frictional resistance reduces . The process of reducing frictional resistance between moving/sliding surface ,by introduction of lubricants in between them is called lubrication . Hydrodynamic Lubrication : Fluid film lubrication is done by introducing sufficiently thick layer ...
