10 Questions
What is lubrication and what is its purpose?
Lubrication is the process of using a lubricant to reduce friction and wear between two surfaces. Its purpose is to allow smooth operation of machine elements, reduce wear, and prevent damage and failure.
What is the study of lubrication called?
The study of lubrication is called tribology.
How do lubrication mechanisms like fluid-lubricated systems reduce friction and wear?
Fluid-lubricated systems reduce friction and wear by carrying the applied load through hydrodynamic or hydrostatic pressure, which reduces solid body interactions.
What are the different lubrication regimes based on?
The different lubrication regimes are based on the degree of surface separation.
What is the purpose of lubrication in a contact between two surfaces?
The purpose of lubrication is to reduce friction and wear and tear.
What happens when lubrication breaks down?
When lubrication breaks down, components can rub destructively against each other, causing heat, damage, and failure.
What are the two main lubrication mechanisms?
The two main lubrication mechanisms are hydrodynamic pressure and hydrostatic pressure.
What is the discipline that studies lubrication called?
The discipline that studies lubrication is called tribology.
Why is adequate lubrication important for machine elements?
Adequate lubrication allows smooth, continuous operation of machine elements, reduces the rate of wear, and prevents excessive stresses or seizures at bearings.
What are the consequences of lubrication breakdown?
The consequences of lubrication breakdown include heat, local welding, destructive damage, and failure.
