Answer:
Explanation:
Some ways to reduce friction are:-
1) Make surfaces smooth by grinding.
Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
2) Using lubricants.
Lubrication reduces the heat generated when two surfaces are in motion. It smoothes the process by forming a film between two surfaces that reduces friction and thus improves performance and efficiency. There are different varieties of lubricants and oils available such as Engine Oil, Hydraulic Oil, and Greases.
