INSTRUCTIONAL OBJECTIVES

Conduct lectures, assign and monitor group projects, assign students software and laboratory projects in addition to homework.

LEARNING STRATEGIES:

Students will be expected to complete their homework, and group project activities and board work during the lectures.

Course Requirements:

Attendance – Attendance is mandatory. Lectures, videos, and class discussions will contain vital information needed to do well on the exams.

Required text: Norton, Richard L., Design of Machinery w/CD, 5th edition, 2008, McGraw Hill, ISBN 978-0-07-352935-6

Exams: There will be THREE exams (this includes the final exam. Exams will be based on text readings, handouts, class exercises, videos, and class lectures and discussions. Students are responsible for all text material, regardless of whether we review the text material in class or not.

Missed Exams: Exams will only be given if you have a documented university excused absence. Realize that the instructor teaches too many classes and has too many students to worry about. She does not simply has the time to make up exams because the student was not responsible to show up to class to take the scheduled exam. If you know in advance that you will miss an exam, you MUST contact me before the scheduled exam. Make-up exams will not contain the same questions and may contain only essay and short answer questions.

Assignments: Homework will be assigned weekly. It will be due one week later in class. In solving the homework problems, the following four steps should be followed very carefully:

1.  Briefly summarize the problem statement.

2.  Provide a schematic diagram of the problem.

3.  Solve the problem showing your work in detail by stating your assumptions and providing the equations you used and the numerical values you obtained.

4.  Write a sentence or two discussing your findings.

Extra credit: There is none.

Grades will be based on:

Exam 1 15%

Exam 2 15%

Homework 10%

Labs/Projects 30%

Quizzes 5%

Attendance/Participation 5%

Final Exam 20%

Grade Distribution

90 - 100 = A

80 - 90 = B

70 -80 = C

60 - 70 = D

Below 60 = F

Disabilities Accommodation:

The University of North Texas complies with Section 504 of the 1973 Rehabilitation Act and with the Americans with Disabilities Act of 1990. The University of North Texas provides academic adjustments and auxiliary aids to individuals with disabilities, as defined under the law. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities. If you believe you have a disability requiring accommodation, please see the instructor and/or contact the Office of Disability Accommodation at 940-565-4323 during the first week of class.

COURSE OUTLINE: The instructor reserves the right to adjust the schedule, add/delete topics that may be relevant to the area.

Additional Policies and Procedures.

My commitment to the students is to train them to the best of my ability to compete in an ever changing technological world. I understand that these students need to be prepared to compete with students with many other higher educational institutions for positions and opportunities. Because of this, I will strive to ensure that the training that they receive is comparable (and may even be better) to the training that other students receive in other institutions . I also want to inform my students that my commitment to their success extends beyond graduation. I want to inform my students that my commitment in providing this training also extends to the community in which these students will eventually end up working in. Under no condition will I certify a student to be competent when he/she has not proven to have reached the level of competence needed to perform engineering work!

Just like I have a commitment to these students, I also have a set of expectations from these students. I expect the students to show up on time; to attend classes and labs regularly; to be respectful of other students , their teaching assistants, and myself; to turn in their assignments as scheduled, and to be ready to learn each and every time we meet. I expect all students to recognize that the teaching assistant that will be assigned for this class is a student who is working under my supervision. I expect all students to show respect and consideration to the laboratory teaching assistant at all times.

1.  All rules relating to academic dishonesty will be enforced in accordance with University policies. Cheating on quizzes, examinations and laboratory assignments, and plagiarism on various papers and reports are types of disciplinary misconduct for which penalties are assessed under the UNT Code of Student Conduct and Discipline. Major responsibility for implementing the University's policy on scholastic dishonesty rests with the faculty. Be advised that the instructor of this course supports and fully implements this policy. The following actions will be taken when evidence of such misconduct is observed. The student will be presented with the evidence of misconduct and given an opportunity to explain same. Based on the outcome of this private conference, the matter will be either dropped or the student will be given a grade of "F" in the course and be referred to the Dean of Students for further counseling and/or disciplinary action.

2.  State common law and federal copyright laws protect my lectures. They are my own original expression and I record them at the same time that I deliver them in order to secure protection. Whereas you are authorized to take notes in class thereby creating a derivative work from my lecture, the authorization extends only to making one set of notes for your own personal use and no other use. You are not authorized to record my lectures, to provide your notes to anyone else or to make any commercial use of them without expressed prior permission from me.

3.  During the course, handouts will be provided to enhance the presentation of certain concepts. These materials are provided strictly for instructional purposes and may other wise be restricted. There is no authorization for further reproduction of distribution of handout materials beyond that intended to teach the course.

4.  This syllabus is subject to change at any time during the semester with changes to be announced in class.

5.  Students should schedule at least one hour per lecture hour for study outside class. Students should schedule at least one hour per laboratory hour for outside work to prepare for the laboratory, use of open laboratory hours, and to complete the required laboratory documentation.

6.  Grades are based, in part, on the student's ability to communicate. Well written English is expected in all course work and is a factor in laboratory report grades. The student’s ability to orally communicate the results of laboratory exercises and class assignments is also monitored.

7.  Each student should retain graded lecture notes, pop quizzes, homework, tests, software-generated files, and laboratory reports to document errors in recorded grades.

8.  Requests for review of graded work must be submitted during the lecture in which such work is returned to the students. The request should be accompanied by a written justification of the request including any supporting data.

9.  The UNT Catalog procedures on cheating and plagiarism will be vigorously enforced. It is the duty of all students to protect their work so it is not available to others for submission as their efforts. This is especially true of files that are generated on the computer. Students who knowingly allow others to use their work are partners in this unethical behavior.

10.  There is no limit to the use of calculators for lecture, labs, pop quizzes, formal tests, or final examination.

11.  Challenges to the course grade must be presented within 60 days of receipt of grade notices mailed by the university. This will insure that instructor’s records are still available to allow a review of the assigned grade. You should first discuss your complaint with the instructor. If you wish to carry it further, contact the Program Coordinator by calling (940) 565-2022. To further pursue your complaint, contact the Department Chair at (940) 565-2022, but ONLY after first discussing your concern with the previous two individuals.

12.  If appropriate, Material Safety Data Sheets (MSDS) are maintained on file in the department for your review. Access to these documents may be provided by the:

·  instructor of this course,

·  Program Coordinator, or

·  Department Secretary.

Seek initial access through the instructor or Coordinator rather than the secretary.

13.  An I (incomplete) grade is given only for extenuating circumstances and in accordance with University and Departmental Policies.
