COURSE DESCRIPTION
Analysis and study of the function, classification, position, velocity, and acceleration of multi-element mechanical linkages and
mechanisms. Synthesis of mechanisms for specified multiple point paths, quick return, dwell, and straight-line motion. The lecture
will instruct students in the kinematic analysis and synthesis of mechanisms through the use of theory and software packages. The
laboratory will familiarize students with a modern mechanism design and animation software package.

simulation.
STATEMENT REGARDING STUDENTS WITH DISABILITIES
Accommodations are collaborative efforts between students, faculty and Disability Access Services (DAS). Students with
accommodations approved through DAS are responsible for contacting the faculty member in charge of the course prior to or during
the first week of the term to discuss accommodations. Students who believe they are eligible for accommodations but who have not
yet obtained approval through DAS should contact DAS immediately at 737-4098."

POLICY REGARDING STUDENT ACADEMIC DISHONESTY AND CONDUCT
Instances of student academic dishonesty and improper conduct will be dealt with according to University policy. Students are
referred to http://oregonstate.edu/admin/stucon/achon.htm for a definition and examples of academic dishonesty and improper
conduct.
GENERAL COURSE INFORMATION
1. Assignments are due in class on the due date.
2. Week 10 lecture homework will not be collected, but students are responsible for the content.
3. Student course notes will be available on Blackboard for each of the instructional lectures. These are partial notes, significant
material is missing. You need to attend class to “fill in the blanks”.
4. Homework (lecture and lab) and exam scores will be posted on Bb. Check often for accuracy.
5. Exercises in Mathematica lectures will not be collected (except week 4), but are strongly recommended to be completed.
ME 412 vs ME 512
Students enrolled in ME 512 are required to submit all of the deliverables for ME 412 (lab and lecture homework, midterm exam, final
exam) in addition to a research paper. This paper will consist, at minimum, of (i) a comprehensive literature review of a topic relevant
to the course, (ii) a proposal for meaningfully extending this body of work. The paper topic must be approved by the instructor.
