## What are the methods of reducing friction explain?

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. Was this answer helpful?

### How are lubricants used to reduce friction in a machine?

Use of lubricants. The use of lubricants like oil and grease helps to reduce friction by forming a thin film between different parts of a machine. This film covers up the scratches and lumps present on the surfaces of different parts and thus makes the surface more even than before. This reduces interlocking between the two surfaces,…

#### How does rolling friction work in a machine?

This reduces interlocking between the two surfaces, and hence the parts of the machine run smoothly. Two moving surfaces in a machine are fixed by placing small balls or rollers made out of steel in between them. This way, the moving parts avoid direct contact and sliding friction is changed to rolling friction.

Is it possible to reduce friction during sliding?

Reducing contact during sliding can reduce friction. But, is it possible? Yes, we can reduce contact by magnetic levitation or by charging both surfaces with the same polarity. Maglev (Magnetic levitation) trains run on the principle of magnetic levitation to reduce friction in order to increase speed and travel experience.

What are two ways you can reduce friction in a machine?

Reducing Friction. 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.

## How can you decrease or increase friction?

We can reduce the friction by using lubricant and increase it by making the surface rough and removing the ball bearing, lubricant, etc. Another important invention similar to the wheel is the invention of a ball bearing. It was possible to reduce the friction greatly between the surfaces by using ball bearing.

### What are three ways to reduce friction?

Generally, there are three ways to reduce friction: 1. The use of bearing surfaces that are themselves sacrificial, such as low shear materials, of which lead/copper journal bearings are an example. 2. Replace sliding friction with rolling element friction, such as with the use of rolling element bearings.

#### How can we increase and reduce friction?

Method of decreasing and increasing friction By polishing: Friction between two surfaces can be reduced by polishing them. Ball-bearing: As the rolling friction less than the sliding friction consequently in rotating machinery, the shafts are fixed on the ball bearing so that the friction can be reduced considerably.
