Why does water or oil reduce friction?

Traditional tribology theory states that, when adding fluid such as oil or water into a dry friction interface, the friction force will usually decrease greatly due to these fluids acting as a lubricant independent of lubrication state; when the external load increases, the friction coefficient might decrease but the …

How do you reduce friction?

Methods for Reduction friction:

1. Make the surfaces little more smoother.
2. Lubrication is another way to make a surface smoother.
3. Make the object more streamlined.
4. Reduce the Normal force acting between the surfaces in contact.
5. Reduce the contact between the surfaces, so that less number of bonds will be formed.

Can we use water as a lubricant?

Water is generally not very good at separating two surfaces that are in contact but it disperses too easily. However, it is quite fluid in movement so if you have a large enough amount of water, it can be a good lubricant but only in specific circumstances.

Is water considered a lubricant?

These results clearly demonstrated that water can be effectively utilized as a lubricant instead of oil to lower the friction and wear of SS components by coating one side with rGO.

Why is water not used as lubricants?

Answer: Lubricants help to reduce friction and yes although water can reduce friction , it is not used as a lubricant . Water is not used as the lubricating strength of water is not as high as oil which is thicker than water . Hence water cannot act as a better lubricant than oil .

How can water be a lubricant?

What are 4 ways to reduce friction?

By polishing the surface, as polishing makes the surface smooth and friction can be reduced. Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.
