6. Justification for new course, including how the course contributes to degree program outcomes,
or other university requirements / student learning outcomes. (Resources, Examples & Tools for
Developing Effective Program Student Learning Outcomes)
The justification for ME 465 – Machine Design II starts with its sister course, ME 365 Machine
Design I. ME 365 is the foundational course in machine design in the mechanical engineering
(ME) curriculum, where it is a required core course in the junior year. It is also a required prerequisite course for capstone and for several upper division technical electives in the “solid
mechanics” emphasis in ME; a similar course is required in all BSME programs across the
country. The ME faculty, through the continuous review process that is conducted as part of
Effective Fall 2015
ABET-accreditation activities, identified some areas of this course where improvement was
needed. A key recommendation that emerged was to cover in more detail topics that are
associated with bolted joints, gears and shafts design. While course changes were made to
accommodate more lectures on gears and shafts design, these took away time from other
topics that are equally important for students’ performance in subsequent courses. As a
result, a survey was carried out to identify practices in other peer mechanical engineering
departments in offering the machine design course. This survey indicated that a significant
number of departments offer two courses in machine design, giving students the opportunity
to immerse in depth in the topics mentioned above, and to also be introduced to additional
topics such as clutches, brakes, flexible mechanical elements, etc. This finding, combined
with the observed increase in DFW rates in the course of up to 20% between 2005 and 2015
triggered the proposed change in this course offering. In addition, the ME department,
informed by its continuous improvement process required for ABET-accreditation, has
decided to make a significant modification to its curriculum in hopes of improving student
performance in machine design. The change is to reduce the breadth of the topics covered on
ME 365 syllabus, thus allowing more depth and mastery of the remaining topics, and to create
a new machine design course, ME 465 Machine Design II, that covers the content dropped
from ME 365, in more depth, and with additional topics appropriate for an ME student (and
covered in other peer departments). ME 465 will be a “required” depth elective for ME students
that elect to focus on the solid mechanics emphasis.

Subject: ME course and program changes
Hi Scott,
Here are the materials for the ME 365, 395, 440 and 465 course changes with syllabi, and the associated program
changes. I have also added my electronic approval.
Please note that on p. 3 of the program of study form, there is a question about whether ENG 105 should be included at
that location (highlighted in light blue). Otherwise, ENG 105 only appears as a footnote in the POS.
Also, I added ME 456 (the new Engineering Modeling of Nonlinear Systems course) to the list of depth electives on p. 4
of the POS, although ME 456 is going through the approval process as well for new course approval.
Thanks,
-Ernesto

Homework/
Quizzes/Exams:
Effective Fall 2015
Reading assignments must be completed before the lecture. The importance of completing
these reading assignments, for your success in this course and beyond, cannot be overstated.
Homework is part of your grade and is due at the beginning of the lecture period. Late
homework will be accepted only under extreme circumstances (e.g., serious illness,
institutional excuse), and will require written verification. If you have an institutional excuse,
arrangements must be made with the instructor prior to the date when you will be absent.
Remember also that you can always turn in an assignment early.
You are strongly encouraged to complete your assigned homework; this will help you better
understand the material. Homework assignments must be done in a professional manner
(neat, orderly, etc.), on engineering paper, using a GIVEN, FIND, SOLUTION format.
 GIVEN: A restatement, in your own words, of the information given in the problem
statement.
 FIND: A statement of what is required to find in the problem from the given information.
 SOLUTION: Your solution to the problem.
When plots or iterative calculations are required in a HW problem, you must use a computer
program to generate the plots/solve the problem. No hand generated plots or calculations will
be graded.
Quizzes will be used to test the completion and understanding of the reading assignments, and
to assess, progressively, the level of understanding of the taught material. All quizzes will be
administered through Bblearn – please complete them as assigned; no make-up quizzes will
be given.
Exams will be used to comprehensively assess the level of understanding of the taught
material. Make-up exams will be given only under extreme circumstances (e.g., serious illness,
institutional excuse), and will require written verification.
It is expected that all your work will be neat, readable, and in logical order. If it is not,
you will not receive partial credit.

Assessment:
The project is a semester long assignment. Students are expected to design a two stage gear
box to be used in either a small wind turbine, weed trimmer, or mini-cart. The gears, shafts,
keys, and bearings will be designed against stress and/or defelection failure. Selection of
materials for the shaft, gears and keys, along with shaft and gears’ finish and heat treatments
is also required. Finally, a gear box casing and lubrication plan have to be included.
Your final grade will be based upon the weighting system provided below. You may receive up to 2%

NORTHERN ARIZONA UNIVERSITY
POLICY STATEMENTS FOR COURSE SYLLABI
SAFE ENVIRONMENT POLICY
NAU’s Safe Working and Learning Environment Policy prohibits sexual harassment and assault, and discrimination and
harassment on the basis of sex, race, color, age, national origin, religion, sexual orientation, gender, gender identity,
disability, or veteran status by anyone at this university. Retaliation of any kind as a result of making a complaint under the
policy or participating in an investigation is also prohibited. The Director of the Equity and Access Office (EAO) serves as
the university’s compliance officer for affirmative action, civil rights, and Title IX, and is the ADA/504 Coordinator. EAO also
assists with religious accommodations. You may obtain a copy of this policy from the college dean’s office or from NAU’s
Equity and Access Office website nau.edu/diversity/. If you have questions or concerns about this policy, it is important that
you contact the departmental chair, dean’s office, the Office of Student Life (928-523-5181), or NAU’s Equity and Access
Office (928) 523-3312 (voice), (928) 523-9977 (fax), (928) 523-1006 (TTD) or equityandaccess@nau.edu.
STUDENTS WITH DISABILITIES
If you have a documented disability, you can arrange for accommodations by contacting Disability Resources (DR) at 5238773 (voice) or 523-6906 (TTY), dr@nau.edu (e-mail) or 928-523-8747 (fax). Students needing academic accommodations
are required to register with DR and provide required disability related documentation. Although you may request an
accommodation at any time, in order for DR to best meet your individual needs, you are urged to register and submit
necessary documentation (www.nau.edu/dr) 8 weeks prior to the time you wish to receive accommodations. DR is strongly
committed to the needs of student with disabilities and the promotion of Universal Design. Concerns or questions related to
the accessibility of programs and facilities at NAU may be brought to the attention of DR or the Office of Affirmative Action
and Equal Opportunity (523-3312).
ACADEMIC CONTACT HOUR POLICY
Based on the Arizona Board of Regents Academic Contact Hour Policy (ABOR Handbook, 2-224), for every unit of credit,
a student should expect, on average, to do a minimum of three hours of work per week, including but not limited to class
time, preparation, homework, studying.
ACADEMIC INTEGRITY
Integrity is expected of every member of the NAU community in all academic undertakings. Integrity entails a firm
adherence to a set of values, and the values most essential to an academic community are grounded in honesty with
respect to all intellectual efforts of oneself and others. Academic integrity is expected not only in formal coursework
situations, but in all University relationships and interactions connected to the educational process, including the use of
University resources. An NAU student’s submission of work is an implicit declaration that the work is the student’s own.
All outside assistance should be acknowledged, and the student’s academic contribution truthfully reported at all times. In
addition, NAU students have a right to expect academic integrity from each of their peers.
Individual students and faculty members are responsible for identifying potential violations of the university’s academic
integrity policy. Instances of potential violations are adjudicated using the process found in the university Academic
Integrity Policy.
RESEARCH INTEGRITY
The Responsible Conduct of Research policy is intended to ensure that NAU personnel including NAU students engaged
in research are adequately trained in the basic principles of ethics in research. Additionally, this policy assists NAU in
meeting the RCR training and compliance requirements of the National Science Foundation (NSF)-The America
COMPETES Act (Creating Opportunities to Meaningfully Promote Excellence in Technology, Education and Science); 42
U.S.C 18620-1, Section 7009, and the National Institutes of Health (NIH) policy on the instruction of the RCR (NOT-OD-10019; “Update on the Requirement for Instruction in the Responsible Conduct of Research”). For more information on the
policy and the training activities required for personnel and students conducting research, at NAU,
visit: http://nau.edu/Research/Compliance/Research-Integrity/
SENSITIVE COURSE MATERIALS
University education aims to expand student understanding and awareness. Thus, it necessarily involves engagement with
a wide range of information, ideas, and creative representations. In the course of college studies, students can expect to
encounter—and critically appraise—materials that may differ from and perhaps challenge familiar understandings, ideas,
and beliefs. Students are encouraged to discuss these matters with faculty.
Effective Fall 2015
CLASSROOM DISRUPTION POLICY
Membership in the academic community places a special obligation on all participants to preserve an atmosphere
conducive to a safe and positive learning environment. Part of that obligation implies the responsibility of each member of
the NAU community to maintain an environment in which the behavior of any individual is not disruptive. Instructors have
the authority and the responsibility to manage their classes in accordance with University regulations. Instructors have the
right and obligation to confront disruptive behavior thereby promoting and enforcing standards of behavior necessary for
maintaining an atmosphere conducive to teaching and learning. Instructors are responsible for establishing,
communicating, and enforcing reasonable expectations and rules of classroom behavior. These expectations are to be
communicated to students in the syllabus and in class discussions and activities at the outset of the course. Each student
is responsible for behaving in a manner that supports a positive learning environment and that does not interrupt nor
disrupt the delivery of education by instructors or receipt of education by students, within or outside a class. The complete
classroom disruption policy is in Appendices of NAU’s Student Handbook.
