Question

8. Material used as a film between two surfaces to reduce friction is known as ________________.
​

Answer 1

Lubricant

Lubrication is the process or technique employed to reduce friction and wear of one or both surfaces in contact and moving relative to each other by applying a substance called a lubricant in between them.

It reduces the maintenance cost of the machine and the heat generation.

Answer 2

Lubrication

• Lubricants are substances that reduce friction by acting as a coating between two surfaces.
• Lubricants are compounds that are used to minimize friction between surfaces and keep wear under control.
• When two surfaces are coated with lubricant, friction is minimized, allowing them to slide over one another when one is pushed against the other.
• Friction is what keeps two surfaces from moving in the same direction.
• Depending on the type of use, some lubricants are more suited than others: the elements of air and water.
