The objective of this course is to extend the concepts learned in all of your courses to
date into the design of a mechanical system. The course will concentrate on the topic
of system design which encompasses component design into the larger concept of
integrating the individual components into a viable system. This course will focus on
the application of sound engineering fundamentals to the representation and solution of
design problems for a mechanical system.

Simply put, my greatest expectation of each individual is that they contribute to the
team progress. 10% of grade is assigned to teamwork. However, if it is determined
that you have not contributed to an individual assignment, you will not receive credit
for that assignment. At the time of each report submittal, you will submit an
assessment of the individual work effort of you and your teammates. In order for you
to receive the teamwork points, you must submit the ratings. If you are not
contributing to the team you will be removed from the team. Removal from a team due
to lack of contribution will bar you from taking ME 4045 in the spring and you will
have to retake ME 4035 in a future academic year.

You will be required to keep a notebook this semester. This notebook will be used to
determine your individual work effort and arbitrate any disputes or issues on your
contribution. The notebook should have the first 2-4 pages left blank for a table of
contents. Entries should be dated at the beginning of each day of your work. The

notebook will be submitted with each report for review. Everything that would
normally be written on an 8 ½ x 11 sheet of paper should be written in the notebook.

Notice that failure to submit your teamwork ratings and notebook on time will result in
you not receiving a numerical grade for those assignments.

In addition to the numerical grade on each assignment, an additional requirement of the
course is that each assignment be completed with a grade of 60 or better. It is also
necessary for you to completely construct your project to your original design intent to
fulfill the requirements of the course. Regardless of your grades on all of your other
assignments, not completing the project will constitute not fulfilling the course

Teams will ideally be formed of 4 students. It may be necessary to have a team of 3 or
5 students, there will be at most only 2 teams of such numbers and there will not be a
team of 5 students if there is a team of 3 students. It has been shown both here and in
other Departments of Mechanical Engineering that 4 student per team provides a
balance of distributed workload as well as requiring individual effort.

It is very important that you join a team with members that have the same
expectations that you do. Specifically, you must coordinate meeting outside of
class either during the day, evening, or on the weekends. In the past, there has
been serious interpersonal conflict between teammates due primarily to schedule
issues and secondarily to expectations of contribution. Friendships have
disintegrated during Senior Design and a common refrain at the end is students
saying that they wished they had not worked with their friends.

Expectations of Project Work

It is fully expected that your project will be completely designed in the Fall semester
and constructed and tested in the Spring semester. Your design is not just that the parts
can be assembled, but you have proven, analytically or numerically, that they will
function (safety, stress, thermal, and other constraints). Your design must be verified
prior to your being allowed to construct it in the Spring semester. Your reports
will be expected to reasonably follow a format provided to you. You are not only
expected to have each section present, you are also expected to have reasonable content
in each section, where appropriate. The final presentation of each will be in front of the
department faculty as well as industrial sponsors or advisors. Each student will be
expected to speak and present a section of the project. You are expected to follow a
reasonable technical format (a sample will also be provided). In addition, you are
expected to be appropriately dressed (a real issue in the past) as well as comport
yourself in an appropriate manner during your group and the other group’s presentation
(another issue in the past).

Late work will not be accepted for this course. Reports are due prior to the start of
class when listed or prior to beginning of the time scheduled for final presentations.

A late or non-submitted project report will be considered to not have met the
requirements of the course and regardless of the points assigned on the original syllabus
and will result in a failing grade for the course. It is required that the report be
submitted in hardcopy form. Electronic submittals are not sufficient, but are required
in addition to the hardcopy submittal.

Do not rely on one person to deliver the report from off campus. It is highly
recommended that someone on campus have at least a draft copy of the report in the
case of any unforeseeable circumstances occurring.

Here is what you really should be doing!

You should show up to every class in order for you and your team to work on project
management issues and meet as a group. The 2 ½ hours per week is a minimum
amount of time required for group meetings. You should keep an engineering
notebook, in ink. You should write weekly progress reports to the team

At the beginning of your project (week 2) your group should create a Gantt chart as a
timeline for your project.

You should actually work like an engineer this academic year.

I will be available in the class during the class time in the classroom assigned for
you to ask questions.

Since this class is largely based upon a group project your and your group’s grades are
dependent on each other. This can result in conflict within the group. You have three
options as an individual. The options are:

1. Accept the grade on the group project determined by the effort of your comrades.
2. Monitor the work of your comrades and ensure that they will help you get the grade
   you desire.
3. Do all the work that your comrades are not doing to ensure the grade you desire.

The prior list illustrates the nature of group projects. Many students operate in option 1
and are disappointed with their final grade. Option 1 is the default and you will reap
your reward accordingly.

If you are having a problem with a teammate or the entire group dynamic you must see
me as soon a possible in order for us all to handle any issues that may arise.

The Fullness of Wings by Gary Dorsey

You are being asked to read a book about the construction of a HPA (human powered
aircraft) that was done by a team from MIT. This vehicle was created to follow the
Daedalus myth of Icarus that flew too close to the sun and the wax holding his wings
on melted and he plunged to his death in the sea.

The purpose for you reading this book is to have a real world account of both the
technical and human issues surrounding a complex technical project. As you read pay
special attention to these issues as well as enjoy reading the book.

Classroom Expectations (this is part of the syllabus)


I have a very simple philosophy of my teaching and of your learning. The first
part of this philosophy is that classes at CU-Denver should be some
reasonable approximation of the level of courses at any other Department of
Mechanical Engineering at other universities. The second is the assumption
that the instructors that you have had in the pre-requisite classes taught you
the material and that you learned the material. The third is a stair case
analogy that a sophomore level course is more challenging than a freshmen
level course, a junior more so than a sophomore, and so on. For example, do
not be shocked if you find that the bar has been raised in the Intermediate
Dynamics course compared to the Introduction to Dynamics course. Finally, I
expect you to put forth some individual effort. This means that I will not spoon
feed you everything. I expect you to be able to think as an engineer,
especially              by            your             junior               year.

While the statements in the prior paragraph may, or perhaps should, be
obvious there is a bit of implication to the statements that is quite serious.

Your grade is not dependent upon whether or not I like you. I will give you the
grade your numerical score deserves relative to the rest of the students in
your class. I have given students that I did not want to spend time with
outside of class A grades and those that I liked F grades. Your relative
performance is what it is.

My office and class are safe zones. This means that the other students and I
will allow you to be yourself regardless of gender, religion, place of origin, and
sexual preference. In fact, I actually find people more interesting the more
different they are from everyone else. Along these lines, if you have a freak
flag, please feel free to fly it in my classes. Of course this does not imply that
you are a freak dependent upon your gender, religion, place of origin or
sexual preference. If you just want to blend in with the crowd, obviously feel
free to do that also.


Past issues with student behavior have lead me to create this list of what is
unacceptable behavior relative to the classroom. Frankly, these topics should
not have to be stated explicitly, but obviously they do.

Overall you are expected to not be disruptive in the classroom and show your
fellow students and the instructor common respect. This results in the
following specific rules.

1. Attendance for the first week of class is mandatory. You will be
    administratively dropped from the course if you do not attend the first
    week of class.
2. You are expected to show up to the class on time and be seated with
    all of your materials already out of your pack or briefcase.
3. You are not allowed to show up late or leave early.
4. You are expected to not be talking to your fellow students during the
    lecture or when someone is asking or answering a question.
5. You are not allowed to eat in class either immediately prior to the class
    or during class. Eat in the hallway. If you eat in class the smell
    permeates the classroom and makes it hard for hungry students and
    the instructor to concentrate. You are allowed to drink non-alcoholic
    beverages in class. However, open pop-top drinks prior to the start of
6. Your assignments are due on the desk or table at the front of the room
    prior to the start of class. It is also expected that homework is turned
    in at the beginning of class, not after the solutions have been written
    on the board. If you are traveling for work, you should fax or scan and
    e-mail your homework. If you are stuck at work, in traffic, or are sick I
    expect you to call my office in advance, leave a message if necessary.
    Taking a vacation during the semester is not a legitimate reason for not
    turning an assignment in on time. If you want to take notes on your
    assignment, you should bring a photocopy with you to class.
7. Derogatory comments about other students, the lecture, or the
    instructor will not be tolerated.
8. You are not to comment negatively about someone else’s ethnicity,
    point of ethnic origin, immigration status, religion, politics, dress,
    weight, or sexual orientation. A distressing number of engineering
    students (and faculty) are prejudiced and homophobic. While it is your
    prerogative to be whatever you desire to be, it is not your prerogative
    to disrupt class with your opinions, comments, or jokes that others will
    find offensive.
9. You are not to use any slurs. One that bears attention is referring to
    someone that is Latino/a or Hispanic as Mexican. When this term is
    used by Anglos it is often (not always) used in a derogatory fashion.
    As one of my students from South America pointed out, a large
    percentage of the Hispanic people in Colorado are from countries other
    than Mexico. Thus for my classes do not use this reference.
10. You are not to use obscenities or similar confrontational language or
    gestures to other students or the instructor. This is regardless of
    whether or not you and the other student(s) are friends and use this
    language outside of class. Specifically, do not say or do the examples
    or other behavior that is obviously equivalent to these examples that
    follow. Here are some examples of unacceptable language or
    gestures that have been used in the past.

         a. Go to Hell!
         b. Screw you! or Fuck you! (this one is simply getting out of hand)
         c. Giving someone the finger.
         d. Grabbing yourself in a sexually suggestive manner.
         e. Threatening violence, regardless of joking.
11. You are not to wear clothing with statements or pictures that are
    inciting or insulting to other students. If you would not reasonably wear
    it to work as an engineer, do not wear it to class. Examples are
         a. Politically charged statements denigrating someone’s political
         b. Explicit or obscene language.
         c. Pictures of males or females that are sexually suggestive. This
            includes silhouettes.
         d. Hats that say such things as border patrol.
12. You are not to discuss your sexual exploits or your visits to strip clubs
    (while not exclusively, this does seem to predominate with the males
    more than the females in the classroom).
13. It is certainly acceptable to participate in the classroom repartee, as
    well as ask someone a quick question if you get lost, I have either
    made an error or I am being particularly obtuse that day.
14. I expect your work to be your own. What constitutes cheating in my
    courses (actually any course)?
         a. You are not to email a computer solution or program to another
            student. Your homework solution should always be in your
         b. If I walk into the laboratory or classroom and someone else is
            holding your solution paper, I consider that cheating. You are
            expected to maintain possession of your solutions. If you are
            showing another student a line or two of your solution, you
            should be clutching your own paper.
         c. I will check your technical writing or other work by doing a
            Google search. If it is found that you have plagiarized
            information that is also considered cheating.
         d. It is acceptable to sit around a table and discuss a problem, it is
            unacceptable to copy someone else's work.
         e. It is clear that there are numerous solutions manuals to the texts
            floating around. It is unacceptable for you to have a solutions
            manual for the textbook for any course. It is also not acceptable
            for you to buy answers from someone over the internet. Don't
            worry, I usually like to make up problems that are not related to
            the book anyway. The recent proliferation of available solutions
            just spurs me to do this more. It is expected in all of your
            classes that you will solve the problems based upon the
            information and methods presented in the class.

   15. It is also your responsibility to let me know if someone is cheating in
       the course.
   16. You are expected to respond to direct questions from the instructor
       and not ignore the question, turn your back or roll your eyes in the
       classroom. Dismissive gestures are also not acceptable.

Let me summarize that I am certainly disappointed that I have to be this
explicit and rigid, but due to the fact that all of the above have not only been
continual problems in courses, the frequency of unacceptable behavior has
been increasing to the point of a fever pitch. On another ludicrous front, the
university forces us to be explicit relative to topics that should be understood
by all of us. I reserve the right to ask you to leave the classroom (either
temporarily or permanently), administratively drop you from the course, or
submit any transgressions of the former specific rules and all general rules
adopted by the university relative to student behavior to the college or
campus disciplinary committee. If you have a specific issue that you do not
feel has been addressed, please bring it up.

You are to refer to me as Dr. Rorrer or Professor Rorrer, not Ron or Rorrer.
You are also to refer to all other faculty by the same titles if appropriate (some
do not have Ph.D.s and thus are not Drs.).

Despite the harshness of the former statements, I do not like the classroom
experience to overly formal. However, in recent years it has had a tendency
to spiral out of control. We both know what reasonable behavior is. There
are three sets of boundaries in the course; your boundaries, my boundaries,
and our group boundaries. Show everyone a reasonable degree of respect
and consideration and there should be no issues. If as an individual you feel
that your boundaries are being infringed upon or violated, see me and we will
address the situation. You also have the right to ask another student to back
off and respect your boundaries.

Finally, I expect you to come by my office if you have questions. I have office
hours when I will always be available, barring any unavoidable conflicts. I am
also available throughout the day. In addition, you can schedule an
appointment if you cannot make office hours. If my door is open, you are
welcome to come by and ask questions. If I am extremely busy, I may ask
you to come by later.
