Question

4. Explain how does lubrication reduce friction
​

Answer 1

Answer:

Lubrication reduces the heat generated when two surfaces are in motion. It smoothes the process by forming a film between two surfaces that reduces friction and thus improves performance and efficiency. There are different variety of lubricants and oils available such as Engine Oil, Hydraulic Oil, and Greases.

Answer 2

A lubricant can be defined as a substance, like as grease capable of reducing friction, heat, and wear when introduced as a film between solid surfaces. It is usually organic, introduced to reduce friction between surfaces in mutual contact, which eventually reduces the heat generated when the surfaces move. Lubricants may also have the function of transporting foreign particles, transmitting forces, or heating or cooling the surfaces.
