WebA useful model for explaining friction is the idea that all surfaces have tiny bumps. When two surfaces slide over one another the tiny bumps push on each other. Friction causes a force on a surface which is in the opposite … WebJun 24, 2024 · How does lubrication reduce friction? Answer: Friction is due to roughness of surfaces. Any process that makes the contact surfaces smooth will reduce friction. Friction can be decreased by adding lubricants to the surfaces like oil, grease or graphite. The sliding surfaces then have a thin layer of the lubricants between them.

WebOct 24, 2024 · Let us find out how lubrication reduces friction. 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 variety of lubricants and oils available such as Engine Oil, Hydraulic ... WebSolution. The friction between lubricant to surface is much less than the friction between the two same surfaces. Hence using lubricants reduces the friction between the two surfaces. When the lubricant is applied to machine parts, it fills the depression present on the surface in contact. Thus, less friction occurs between machine parts.

WebMar 5, 2024 · Fluid friction; Choose the right lubricant. To ensure performance at optimal levels, bearings often require sufficient lubrication. Only when it is properly applied, lubricants reduce friction and bring down the amount of wear and tear. Thus, lubricants play a vital role in the performance, maintenance and efficiency of these equipment’s. WebLubrication reduces friction and allows moving machine parts to slide smoothly past each other. An automatic lubrication system has many advantages compared to manual …
