Question

Suggest one way each of increasing
and decreasing friction in machines.​

Answer 1

Answer:

Method of decreasing and increasing friction

By polishing: Friction between two surfaces can be reduced by polishing them. Ball-bearing: As the rolling friction less than the sliding friction consequently in rotating machinery, the shafts are fixed on the ball bearing so that the friction can be reduced considerably.
