graphite is applied between the moving parts of a machine why
Answers
We sprinkled fine powder on the carrom board. When a few drops of oil are poured on the hinges of a door, the door moves smoothly. A cycle or a motor mechanic uses grease between the moving parts of the cycle. In all the above cases, we tried to reduce friction in order to increase efficiency. When oil, grease or graphite is applied between the moving part of a machine, its thin layer is formed there and moving surfaces do not directly rub against each other. Interlocking of irregularities is avoided to a great extent. Movement becomes smooth. The substances which reduce friction are called lubricants. In some machines it may not be advisable to use oil as lubricant. There is an air cushion between the moving parts, that is used to reduce friction.
