REDUCING FRICTION

Methods of Reducing Friction:

Friction is the force that opposes motion between two surfaces in contact, can be reduced by changing the nature of the surfaces in contact, the force acting on them, or the environment in which they are in.

Some methods of reducing friction are:

  • a.Lubrication:

applying a lubricant, such as oil or grease, between two surfaces reduces friction by creating a barrier that prevents direct contact between the surfaces.


  • b.Surface Finish:

 improving the surface finish of the materials in contact can reduce friction by reducing the number of points of contact between the surfaces.


  • c.Rolling Friction: 

converting sliding friction to rolling friction by using wheels or rollers instead of sliding surfaces can reduce friction by decreasing the area of contact between the surfaces.


  • d.Vacuum:

reducing the air pressure between two surfaces in contact can reduce friction by reducing the forces acting on the surfaces.


  • e.Temperature:

 increasing the temperature of the surfaces in contact can reduce friction by reducing the viscosity of the lubricant and making it easier for the surfaces to slide past each other.
