Question

a large amount of fuel is wasted while running machines to a) reduce friction b) increase friction c) overcome friction d) minimise friction​

Answer 1

Answer:

option d is correct one

Answer 2

Answer:

A large amount of fuel is wasted while running machines to reduce friction.

Explanation:

• The force that opposes an object's motion on the surface it is in touch with is known as friction.
• When there are irregularities on the two surfaces that are in touch with one another, friction occurs. As a result of these irregularities interlocking, friction is created.
• Thus, it may be said that friction depends on the surface's smoothness and roughness.
• Friction may be classified as static friction, rolling friction, sliding friction, and fluid friction.
• Because no surface is completely smooth and always has some irregularities, friction cannot be completely eliminated.
• However, the use of lubricants can either minimize or reduce friction.
• Grease and other lubricants, such as castor oil, aid in reducing friction and are used in machines to both make work more smoothly and lessen the wear and tear on the surfaces that come into contact.
