Question

friction can be reduced by ​

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.

Improve overall lubrication either by changing viscosity, using differing or improved additives or through the use of different lubricants themselves, i.e., synthetics, solids, etc.
