How the use of oil reduces friction between two surfaces in contact with each other.

Open in App

Solution

When oil is applied between the two surfaces in contact, a thin layer of oil is formed between the two surfaces. This layer separates the two surfaces a little bit due to which their interlocking is reduced to a large extent when they rub against each other.
