What is lubrication?
Q: What is lubrication?
A: Lubrication is a physical process that enables surfaces to move smoothly against each other.
Q: How does the use of lubrication help surfaces?
A: The use of lubrication reduces friction and wear on surfaces, preventing them from overheating.
Q: What are some examples of lubricants?
A: Some examples of lubricants include oil used in machinery, tears in eyes, and synovial fluid in joints.
Q: What types of lubricant films are there?
A: There are four types of lubricant films, which include solid/liquid dispersion, liquid, liquid-liquid dispersion (a grease), or exceptionally, a solid or gas.
Q: What is the function of a lubricant film?
A: The function of the lubricant film is to reduce friction, wear on surfaces, and prevent temperatures from rising too far.
Q: How does the use of lubrication affect machinery?
A: The use of lubrication reduces friction and wear on machinery, thus extending its lifespan and reducing the need for maintenance.
Q: How does our body use lubrication naturally?
A: Our body uses lubrication naturally by producing synovial fluid in our joints, which prevents friction and wear between them. Also, tears in our eyes contain a lubricant that helps us blink without hurting our sensitive eyes.
