Lubrication - Fundamentals
Edward Brunet, Jr., P.E.
Overview
Friction is a force that resists relative motion between
two surfaces in contact. Friction can be beneficial, such as when
attempting to plant your feet to move a heavy object. However, friction in
rotating equipment can be detrimental. Excessive friction causes premature
wear and generates heat, which results in wasted energy.
In this course, the student will learn the basics of
friction and wear and how lubrication is used to reduce friction in common
applications. The course will cover Chapter 2, "Lubrication Principles" in
the US Army Corps of Engineers document EM 1110-2-1424, "Lubricants and Hydraulic
Fluids".
The student must take a multiple-choice quiz consisting of
ten questions at the end of
this course to obtain PDH credits.
