Answer 2

Answer:

1. by using lubricants :- friction increases as the roughness of the surface increases.

2. polishing surfaces :- it makes the surfaces even and hence reduces friction.

3. by using ball bearings :- Rotating machines can be mounted on ball bearings.

4. by streamlining :- streamlining reduces the area of contact and thus reduces friction.
