Methods of Reducing Friction
Friction can be reduced by the following methods:
1) The various parts of the machines which are moving over one another are properly lubricated.
2) In machine the sliding of various parts is usually replaced by rolling and it is done by using ball bearings.
3) Where sliding in unavoidable, a thick layer of greasing material is used between the sliding surfaces.
4) The front of the fast moving objects e.g. cars, Airplanes is made oblong to decrease air friction.
