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:

lubrication is the main way to reduce friction. metal balls are used in machines to reduce friction
