Question
Mention any three ways of minimizing friction.
Solution
- By using lubricants:
These are applied to surfaces to reduce the friction between the surfaces. Example Oil, wax, grease, and castor oil. - With the help of polishing the surface:
We sprinkle the fine powder on the carrom board and then we polish its surface to make it smooth so that the striker slides easily on the surface. - By using ball bearing:
We use lead shots in the bearing of a cycle hub because rolling friction is smaller than sliding friction.
