Question

Suggest some methods to reduce friction.

Comments

Improve surface finish.
Apply lubricant.

Answer 1

Some methods to reduce friction are as follows:

• Lubricating oil and grease are used in machines to reduce friction between moving parts.
• Some machines use air cushion for reducing friction because use of oil is not ideal in such machines.
• Graphite powder is used in some machines to reduce friction.
• Ball bearing coverts sliding friction into rolling friction. You have read that rolling friction is less than sliding friction. Thus, ball bearing helps in reducing friction.
