Statement
of Purpose:
Most engineering science courses
teach fundamental knowledge and quantitative theories. M&AE 2250 is a
different type of course, one focused on design. Design has no unique path of
progression or definitive ÔrulesÕ – each design task may follow different
methods of approaching the problem. You will learn the values and priorities
that help you create and select solutions that meet customer specifications
with constraints given by manufacturability. You will cultivate an ability to work
with teammates and to function in a project having ÔfuzzyÕ objectives. Design education is challenged by a qualitative
nature, a wide-ranging technical content and personal preferences of individual
designers.
Overall, MAE 2250 should
¥ Stimulate original thinking and creativity;
¥ Integrate engineering knowledge with personal
experience in multi-disciplinary applications;
¥ Foster an understanding of the unstructured
nature of design;
¥ Provide practice in problem definition and
solution synthesis;
¥ Provide training in graphical thinking and
communication;
¥ Introduce fabrication methods necessary for
practical implementation of designs;
¥ Introduce critical economic evaluation of design
concepts.
You will experience a
comprehensive ÒProduct RealizationÓ process. You will design and produce devices,
systems or processes to meet ÒcustomersÕ needs,Ó including considerations of
performance, cost, manufacturing, marketing, etc. You will interact with others
and apply design methodology. This course is built around design projects, not
homework or exams. These design experiences will simulate real-world
engineering practices and include system/project approaches, teamwork, and
graphic and oral communication.
Course
Objectives:
To
introduce the product realization process
To
explain and apply mechanical design methods
To provide group interaction experiences
To design and manufacture
mechanical devices
On completion of the course, students should
á Be familiar with the product realization process
and its documentation. (ABET c).
á Be able to formulate and solve simple models to
analyze a design. (ABET a & e)
á Appreciate wider design issues such as ethics,
liability, safety, and product disposal. (ABET f).
á Be familiar with basic communication techniques
(written, oral). (ABET g).
á Be familiar with basic tools of design and
manufacturing such as CAD and machine tools. (ABET k).
á Be cognizant of safety in manufacturing.
á Function effectively in a team. (ABET d).
á Gain an appreciation for analytical courses to
follow MAE 2250.
There will be three main projects
in this course: (i) you will manufacture a metal object in the Emerson Shop from
a specified set of drawings, (ii) teams of four or five students will design,
analyze and build a water pump, (iii) the same teams will pursue and
open-design project to fulfill an identified consumer need.
Staffing
and office hours:
For list of faculty and staff by
section (with NetIDs) see TA Coverage page.
TA Office Hours will be held in
the Taylor Studio or in Emerson.
Instructor office hours are held
in 236 Thurston, one hour immediately after class.
Website:
http://courses2.cit.cornell.edu/mae2250/
Course information and handouts
will be posted on the site for download.
Schedule:
For a tentative schedule of
topics and activities, see week-by-week schedule
Laboratory:
Assigned as scheduled by the
Registrar.
All
labs will meet in the Taylor Design Studio, 265 Upson. Sometimes, some of the
students will walk over to Emerson.
Switching Sections:
Laboratory sections can only be changed if the following conditions are
met:
(1) you
find a ÒpartnerÓ in the desired lab section to swap with.
(2) BOTH of you together meet
with Nanette Peterson (Upson 108) to implement the switch.
(3) In that meeting, Nanette will
give you a signed form to present to your new TA.
Taylor
Design Studio:
Taylor design Studio will be open for sections and additional office
hours. See contacts page.
Emerson
Shop:
The Emerson Shop is open for regular sections and suring
additional hours. No food or drinks. Closed shoes, no loose clothing,
loose jewelry, or loose hair.
No students may leave the lab
until everything is cleaned up in either Emerson or the Design Studio. Clean-up
will start 15 minutes before the scheduled end of lab section and continue
until completed. Failure to clean-up will result in loss of shop privileges.
Consult Emerson Shop Rules and Emerson Machining Guide for more information.
Grading:
Your final grade will be
determined from the class activities as follows:
Projects |
Shop practice (Lamp)
10% CAD Project
10% Open Product Design
40% Water pump Project
40% Bonus Homework assignments 5% |

Grading in this course is Òprocess
gradingÓ, which is quite different from what you are used to. Your grade is
based primarily on the process you went through as evident from your
participation, design notebook and attendance. A team will receive one grade
per project, but this grade can be rebalanced by peer evaluation within the
group and by notebook evaluation. The emphasis is on engineering practice
activities.
Assignments must be turned in to
your section TA by beginning of section on the due date. Late assignments will
be penalized 5% per 24H late. No credit will be received for assignments turned
in more than a week late.
Final exam material will cover
textbooks Budynas & Nisbett
chapters 7-17 and Dieter & Schmidt, as well as material covered in class
(see posted lectures).
Laboratory
Fee:
Laboratory fee will be billed to
your BursarÕs bill to cover materials and supplies.
Attendance:
Lab attendance is essential to an
active experiential learning course. Absence will be penalized by reducing your
final course grade by 5% for each laboratory missed. Missing 3 or more
laboratory sessions will result in an automatic ÔFÕ. Many lab meetings will
start with a group exercise requiring your attendance. If you are late to any
lab or shop activity, your grade will be reduced by 2% for each such lateness.
Lecture attendance is recommended
but not mandatory.
Safety:
Improper, irresponsible or unsafe
behavior will result in loss of laboratory privileges in both Emerson and the
Design Studio. Due to the high fabrication content of this course, this policy
will be strictly enforced. Grades may also be used to penalize safety. Safety
is so important that a serious infraction is an automatic ÔFÕ in the course.
Before working in the Emerson
Shop, you will be required (1) to read the ÒEmerson Shop RulesÓ and the "Introduction to Machining PracticesÓ found on the Course website and (2) to turn in
your signed ÒMachine Shop ContractÓ found at the end of the Shop Rules as
evidence that you read and understand these.
Project
Notebooks:
Project notebooks are an
essential part of design realization and are required. Project notebooks (one
per team) will be uploaded to CMS at the end of every week for grading and
feedback. At the end of each project, the project report will be a significant
portion of your grade.

Academic Integrity
Students are allowed to share
ideas but not written work, except team-project work within the same team.
Students may not copy any part of
someone else's work (including from other students, external sources, previous
years, the Internet, etc.) unless they explicitly mention the source and
provide a citation, and then they will be judged by their added value compared
to the source. If copying text verbatim, put copied text in quotes and cite
source. If paraphrasing someone else's idea, cite original source. Copying
without attribution is considered plagiarism and a violation of academic
integrity.
Students with Disabilities
If you are a student with a
documented disability on record at Cornell University and wish to have a
reasonable accommodation made for you in this class, please see the instructor
immediately.
