Lubricants:- Lubricants   May be defined as a substance which reduces the friction when introduce between two surface.This phenomenon is known as an lubricantion. Types of lubricants:- 1- Solid lubricants 2. Lquid lubricants & 3. Semi-solid lubricants Functions of Lubricants:- a) It reduces the frictional resistance between moving parts. b) It reduces the surface deformation. c) It act's as a seal in some cases. d) It to improve the efficiency of the machine. e) It helps transfer heat and cool engine parts.etc.... We will talk about the next topic later. So stay with us thank you.
