About Lubricating Oil .....
Answers
Answer:
Uses of Lubricating Oils: Lubricating oil provides a coating to prevent contact between two metal surfaces of moving parts. The protecting layer formed by lubrication helps to maintain component surfaces from rust and corrosion. Lubricating oil absorbs heat, moving it away from surfaces.
Explanation:
Lubricant forms an oil film on the surface of metals, converting solid friction into liquid friction to reduce friction, which is the most common and essential function of lubricants. Reduced friction prevents heating and abrasion on the friction surface.
The way to reduce friction between two moving parts is to lubricate them (coat them in oil)—but how does lubrication actually work? Solids are materials that have a built-in resistance to changing shape, whereas liquids can flow.Jan 27, 2019
Properties of Good Lubricants. Suitable Viscosity: The viscosity of oil should not change with rise in temperature. Oilness: It ensures the adherence to the bearings and spread over the surface. This property makes oil smooth and very important in boundary lubrication.
A lubricant is a substance, usually organic, introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces
