During this course we will discuss (1) the wear and friction of solids (2) the laboratory equipment used in
tribological investigations (3) and theoretical and empirical models for wear.
Wear
II.5.a The process or condition of being worn or gradually reduced in bulk or impaired in quality by
continued use, friction, attrition, exposure to atmospheric or other natural
destructive agencies; loss or
diminution of substance or deterioration of quality due to these causes.
II.6.a wear-and-tear wearing and damage due to ordinary useage; deterioration in the condition of a
thing through constant use or service
Friction
[a.F. friction, ad.L friction-em, n. of action from ficare to rub]
2. The rubbing of one body against another; attrition.
3. Physics and Mech The resistance which any body meets with in moving over another body.

Textbook (Suggested)
Friction and Wear of Materials

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. In the main, the work should be yours.
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.
Grading
Homework is 40%, the midterm exam is 30%, and the final exam is 30%.
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.
Following the request of the Provost I include the following statement.
All students admitted to the university of Florida have signed a
statement of academic honesty committing themselves to be honest in all
academic work and understanding that failure to comply with this commitment
will result in disciplinary action.
This statement is a reminder to uphold your obligation as a student at the
University of Florida and to be honest in all work submitted and exams taken
in this class and all others.
