Question

The force of friction between two surfaces can be reduced by _____ them​

Answer 1

Explanation:

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:

The force of friction between tow surfaces can be reduced by sliding friction.
