"The word 'tribology' was coined only just over twenty five years ago and appears in only the most up to
date of dictionaries; however, the topics with which tribologists are concerned have been of vital interest to
scientists, engineers, and those who design or operate machinery, for as long as mechanical devices have
existed. Formally, tribology is defined as the science and technology of interacting surfaces in relative
motion and of related subjects and practices; it deals with every aspect of friction, lubrication, and wear."

Homework
Four homework sets will be assigned and graded. At least one week is given for the completion of a homework set. The
purpose of the homework is to aid in learning the material. To this end some collaboration among students in
preparing the homework is acceptable. However, in the main, the work should be primarily yours. In an effort to
increase the value of the homework, solutions will be posted on the internet the day after it is due and discussed
in the next available class period. Because of this tight timeline, late homework will not be accepted.
Exams
There will be two examinations, a midterm and a final examination; these tests are open notes closed text.
Project
There will be a written and oral project, which is a literature review of a current topic in tribology research of
the students choosing.
Grading
Homework is 25%, the midterm exam is 25%, the project is 25%, and the final exam is 25%.
Attendance and Class Participation
I consider attendance mandatory, and good class participation will be given consideration during the determining
of final grades.
Academic Integrity
As is understood by the vast majority of students, our basic relationship is based on trust; I have never
encountered a problem in this area. Please familiarize yourself with the Student Guide, the honor code, and the
implied pledge - which accompanies all work submitted for credit.
