Question

Regular oiling and polishing increase the life of a machine.

• A. True
• B. False

Answer 1

The correct option is A True

1. Friction is defined as the resistance offered by the surfaces that are in contact when they move past each other.
2. The frictional force causes wear and tear of the machine parts.
3. Oiling and polishing reduces friction and consequently prevent the wear and tear of the machine parts.
4. Due to less wear and tear due to the oiling and polishing, the life of a machine increases.

Hence, the given statement is true.
