Question

Discuss two methods to reduce friction with example.?
​

Answer 1

Answer:

There are several ways to reduce friction: The use of bearing surfaces that are themselves sacrificial, such as low shear materials, of which lead/copper journal bearings are an example. Replace sliding friction with rolling element friction, such as with the use of rolling element bearings.

Answer 2

Answer:

1) using lubricants such as water or oil. These liquids will fill the gaps present on the surface and make the surface smoother thus reducing friction.

2) polishing - polishing the surface can help reduce friction
