Course Expectations

COURSE PRE-REQUISITES

 MENG 3233 Mechanisms & Dynamics of Machines.

OTHER PREREQUISITES

Basic computer skills, SolidWorks, SolidWorks Simulations, MS Excel, hand calculator

Lecture

This course consists of a three 50-minutes sessions and two hours lab per week. The three hours class will be spent mostly explaining and discussing concepts, and solving relevant case problems. The other two hours will be dedicated to lab experiments, result analysis, and lab reports. Lectures will not be used to communicate the entire textbook course content and thus, students will have to study a set of course paragraphs specified by the instructor on their own to further their understanding. Student participation in class discussions is highly recommended and rewarded.

Exams

There will be two midterm exams plus one final exam at the end of the semester. Each exam is based on two testing parts. A Theoretical part (closed book) designed to test the students’ ability to master the taught materials. This testing part includes textbook questions and short problems. A 8.5”x11” sheet is allowed for personal notes. A practical part (open book) is designed to test the students’ ability to analyze and solve a set of problems on their own. Each exam is based on the course materials developed between two consecutive exams. You are expected to take the exam on the scheduled date and time it is given. However, if for a major and acceptable reason you are unable to do so, then you must inform the instructor in advance in writing and give a valid proof of your absence. The instructor will give then a make-up exam toward the end of the semester. The examination materials for the make-up exam may be very different from the ones given in regular exams. For those who did not have a valid reason for missing the exam, their grade will be 0%. It is absolutely forbidden during the exam session to use cell phones and/or other electronic devices with the exception of a simple hand calculator.

Homework and Quizzes

Homework will be assigned from a set of chosen chapters by the instructor. Homework must be turned in on the due date at the beginning of class, 20% of the grade. Once class starts, homework will still be accepted for a grace period of 48 hours, 10% of the grade. After the grace period, homework will be accepted till the end of the semester, 0% of the grade. A quiz on the homework will be graded between 0% and 80 %. The goal of the quizzes is to encourage the students to study the course materials and do the homework by themselves. Quizzes will consist of true/false, multiple choice types of questions and/or short problems related to the current homework. You are expected to take these quizzes on scheduled dates and times specified by the instructor. However, if for a major reason you are unable to do so, then you must provide the instructor with a valid written excuse. For those who missed quizzes with a valid reason, the instructor will then give a make-up quiz at the end of the semester. The examination materials for the make-up quiz may be very different from the missed one. For those who did not have a valid reason for missing the quizzes, their grade will be 0%. It is absolutely forbidden during the quiz session to use cell phones and/or other electronic devices with the exception of a simple hand calculator. Each student is responsible for submitting his own individual personal homework and quiz copy, written in his own words. No dual or group homework copy is accepted unless specified by the instructor.

GENERAL GUIDELINES

 

  • Plan on spending at least 6 hours outside of class to study the material and to work on homework assignments, and lab experiments. Do not wait until the last day to start working on your report, or prepare for the exam.
  • Read the course material before coming to class.
  • Utilize the office hours throughout the semester to seek explanations from the instructor.
  • Use engineering paper for all homework assignments and exams. Use a systematic approach to solve problems. If a problem involves drawing a graph, use Excel, Matlab, or any other graphic software tool to draw the graph. In engineering, neatness is a must, not a luxury. Be advised that you will be penalized for a lack of neatness.
  • You are strongly encouraged to study in group. Time to time a lab partner will be randomly selected for you.

 

Grading Standards

Course Grade

The final grade for the course will be based on the scores earned in the two mandatory partial exams, the mandatory final exam, the average score earned in the homework and quizzes, the average score earned in the lab reports, and the class attendance, participation, and attitude score earned by the student. The first exam contributes 10%, the second exam contributes 20%, the final exam contributes 30%, homework average contributes 10%, lab reports average contributes 20%, and class attendance, participation, and attitude, contribute 10%, for a total of 100%. The overall average score (X) for the course is determined as follows:

X = 0.10 x exam1 score + 0.20 x exam 2 score + 0.30 x final exam score + 0.10 x (homework + quizzes average scores) + 0.20 x (lab report average score) + 0.10 x (participation/attitude/attendance scores) = 100%.

The final letter grade for the course is based on the value of X and is determined from the following grade levels:

 

Value of X (in %) 90 - 100 80 - 89 70 - 79 60 - 69 <60
Letter Grade A B C D F

 

Final Exam 12/11/2017 8:00-10:00 am
Submission Format Policy

Students in this course must demonstrate their competency in oral and written communication through written homework assignments, lab reports, quizzes, and exams. They must also demonstrate their ability to use the English language.

Exams, Homework, Quizzes and Labs

Use the formats posted in D2L.

 


Note: You may not submit a paper for a grade in this class that already has been (or will be) submitted for a grade in another course, unless you obtain the explicit written permission of me and the other instructor involved in advance.
Late Paper Policy

Plagiarism Policy

Plagiarism is the use of someone else's thoughts, words, ideas, or lines of argument in your own work without appropriate documentation (a parenthetical citation at the end and a listing in "Works Cited")-whether you use that material in a quote, paraphrase, or summary. It is a theft of intellectual property and will not be tolerated, whether intentional or not.

Student Honor Creed

As an MSU Student, I pledge not to lie, cheat, steal, or help anyone else do so."

As students at MSU, we recognize that any great society must be composed of empowered, responsible citizens. We also recognize universities play an important role in helping mold these responsible citizens. We believe students themselves play an important part in developing responsible citizenship by maintaining a community where integrity and honorable character are the norm, not the exception.

Thus, We, the Students of Midwestern State University, resolve to uphold the honor of the University by affirming our commitment to complete academic honesty. We resolve not only to be honest but also to hold our peers accountable for complete honesty in all university matters.

We consider it dishonest to ask for, give, or receive help in examinations or quizzes, to use any unauthorized material in examinations, or to present, as one's own, work or ideas which are not entirely one's own. We recognize that any instructor has the right to expect that all student work is honest, original work. We accept and acknowledge that responsibility for lying, cheating, stealing, plagiarism, and other forms of academic dishonesty fundamentally rests within each individual student.

We expect of ourselves academic integrity, personal professionalism, and ethical character. We appreciate steps taken by University officials to protect the honor of the University against any who would disgrace the MSU student body by violating the spirit of this creed.

Written and adopted by the 2002-2003 MSU Student Senate.
