Homework: Is due at one week after it is assigned, unless there is a holiday. See above. It should be emailed to MEE120section3@gmail.com as a single .zip file. Do not worry about the section number.

Late Work Policy: Late work is not acceptable in any organization. Late assignments will be refused by the instructor and given a zero unless there is a prior arrangement.

Regrading and Resubmissions: Some schools allow students to keep revising and resubmitting homework until they get the grade they want. That will not be allowed. There will be no regrading unless there is a grading error. If you have questions ask them before the deadline.

Prerequisite: MEE major or permission

Optional Textbook: None

Recommended Text: Modern Graphics Communications, Giesecke, F.E. et al., Peachpit Press, 2009

Required Hardware: Windows laptop capable of running required software; 3-button, scroll wheel mouse

Required Software (included with course): SolidWorks Education Edition 2022-2023. If you show up for an exam with the wrong version of SolidWorks and can not open the exam you will be given a zero. Special exams will not be created.

Required Drawing Tools: Pencils, erasers (white polymer recommended), ruler (in/cm).

Course Objectives: Upon satisfactory completion of the course, students will be capable of producing elementary sketches, graphs, and SolidWorks drawings of typical engineering and structural objects. Students will understand basic graphical principles and be able to apply these principles to graphical communications.

Course Outcomes: By the end of the course, students will demonstrate an ability to:

Communicate mechanical designs via freeform, orthographic and axonometric hand sketching
Read and interpret mechanical drawings
Demonstrate familiarity with the fundamental concepts of fits, tolerances
Apply a Parametric Solid Modeling CAD package to:
1. Construct robust sketches that reflect appropriate design intent
2. Construct mechanical parts using extrude and revolve
3. Modify parts using fillets, chamfers, holes, and patterns
4. Construct assemblies of parts
5. Produce engineering drawings of mechanical parts and assemblies, in accordance to a specified drafting standard

Topics: See the “Lessons” page of this website

Final Project: The final project will consist of a CAD design package for a Stirling engine.

Cheating will result in an instant F for the course and the matter will be turned over to the department disciplinary board. Just don’t do it…I check. You are paying a lot to be in this class. Don’t waste your money.

Campus Policies:

Academic Honesty Statement: Academic honesty is very important. It is dishonest to cheat on exams, to copy term papers, to submit papers written by another person, to fake experimental results, or to copy or reword parts of books or articles into your own papers without appropriately citing the source. Students committing or aiding in any of these violations may be given failing grades for an assignment or for an entire course, at the discretion of the instructor. In addition to any academic action taken by an instructor, these violations are also subject to action under the University of Maine Student Conduct Code.

The maximum possible sanction under the student conduct code is dismissal from the University.

Students with disabilities statement:

If you have a disability for which you may be requesting an accommodation, please contact Student Accessibility Services, 121 East Annex, 581.2319, as early as possible in the term. students who have already been approved for accommodations by SAS and have a current accommodation letter should meet with me (the instructor of the course) privately as soon as possible.

Sexual Discrimination Reporting:

The University of Maine is committed to making campus a safe place for students. Because of this commitment, if you tell any of your teachers about sexual discrimination involving members of the campus, your teacher is required to report this information to the campus Office of Sexual Assault & Violence Prevention or the Office of Equal Opportunity.

Behaviors that can be “sexual discrimination” include sexual assault, sexual harassment, stalking, relationship abuse (dating violence and domestic violence), sexual misconduct, and gender discrimination. Therefore, all of these behaviors must be reported.

Why do teachers have to report sexual discrimination?

The university can better support students in trouble if we know about what is happening. Reporting also helps us to identify patterns that might arise – for example, if more than one victim reports having been assaulted or harassed by the same individual.

What will happen to a student if a teacher reports?

An employee from the Office of Sexual Assault & Violence Prevention or the Office of Equal Opportunity will reach out to you and offer support, resources, and information. You will be invited to meet with the employee to discuss the situation and the various options available to you.

If you have requested confidentiality, the University will weigh your request that no action be taken against the institution’s obligation to provide a safe, nondiscriminatory environment for all students. If the University determines that it can maintain confidentiality, you must understand that the institution’s ability to meaningfully investigate the incident and pursue disciplinary action, if warranted, may be limited. There are times when the University may not be able to honor a request for confidentiality because doing so would pose a risk to its ability to provide a safe, nondiscriminatory environment for everyone.

If the University determines that it cannot maintain confidentiality, the University will advise you, prior to starting an investigation and, to the extent possible, will share information only with those responsible for handling the institution’s response

The University is committed to the well-being of all students and will take steps to protect all involved from retaliation or harm. If you want to talk in confidence to someone about an experience of sexual discrimination, please contact these resources:

For confidential resources on campus: Counseling Center:207-581-1392 or Cutler Health Center: at 207-581-4000.

For confidential resources off campus: Rape Response Services: 1-800-310-0000 or Spruce Run: 1-800-863-9909.

Other resources: The resources listed below can offer support but may have to report the incident to others who can help:

For support services on campus: Office of Sexual Assault & Violence Prevention: 207-581-1406, Office of Community Standards: 207-581-1409, University of Maine Police: 207-581-4040 or 911. Or see the OSAVP website for a complete list of services at http://www.umaine.edu/osavp/

FINAL EXAM

Eating and drinking in classrooms: Students may not eat or drink in the classrooms and are encouraged to take their food or drink into areas designated for these purposes.

Contingency plans: Classes will be held in various formats to offer flexibility, compassion, and empathy during these unprecedented times. Under certain circumstances, students or instructors may need to miss classes or in-person classes may be disrupted. Students are expected to notify their instructor if they are unable to attend an in-person or online class but will not be penalized for missing class due to illness or the need to care for a family member affected by COVID-19. If a disruption occurs, your instructor will provide communication and contingency plans.

What to do if you have or suspect you have COVID-19: If you have symptoms of COVID-19 or have been possibly exposed to someone with COVID-19, you should stay home, not interact with others, and contact your health care provider immediately to be tested for COVID-19. You may not attend in-person classes and should suspend interactions with others until you are tested. Prior to receiving test results you should quarantine in your living area according to the Maine CDC guidelines below. Please follow the guidance of your health care professional regarding testing, quarantine, and isolation during the testing process and potential illness period.
