Course Description:
ET 271. Engineering Statics. Credit 3 hours. Prerequisites: Mathematics 200 and Physics 191. This course uses vector methods for the study of force, coupled and equivalent force systems, equilibrium of particles and rigid bodies, centroids, centers of gravity, moments of inertia, and virtual work. It includes analysis of simple structures such as trusses and beams, applications of dry friction models to belts and wedges, and the method of virtual work.
Course Objectives:
Study and apply the following principles to solve practical problems:
· Vector methods in rigid-body mechanics
· Mechanics of objects at rest or in uniform motion
· Mechanics of distributed loading, simple trusses, belts, wedges, and screws
· Moments of inertia
· Principle of Work and Virtual Work
Textbook: Engineering Mechanics: Statics (10th ed) by R C Hibbeler.

Grading System:
1. Basis for assigning grades:
Two Tests = 100 Points @ 50 points each
Final Exam = 100 Points
Project = 100 Points
Homework = 100 Points
Quiz = 50 Points
Attendance = 50 Points
______
TOTAL 500 POINTS
______
2. Based on the total percentage scored out of 500 points, the final letter grade will be assigned according to the following scale:
90-100% = A – Excellent
80-89% = B – Very Good
70-79% = C – Average
60-69% = D – Below Average
0-59% = F – Failure
Note 1: Students MUST score a “C’ or above in all courses within their major. Otherwise, they must repeat the course.
Note 2: All students are expected to take tests on the specified date and time. Students with unexcused absences will not be able to make-up tests, quizzes and lab assignments! A grade of Zero (0) will be assigned!
Note 3: All grades will be posted on Blackboard when they are ready. Please check your grades on Blackboard regularly, so that you can keep track of your overall grade in this course at any given moment. Let me know if you observe any discrepancy or error in your grade postings.
If you have any problem with this grading system, please make an appointment to discuss with me immediately!

FINAL EXAM
/ 09 December 2010 / Thurs / 12:30-02:30 pmUniversity Policy Requirements:
· You are expected to adhere to all departmental policies and procedures.
· Please also review the campus correspondence sent out to all faculty by the Provost, which can be found on the SLU website.
· Assignments and Tests/Quizzes: Late assignments will be penalized. Students who have unexcused absences will receive the grade of "0" for all assignments and tests missed.
· Attendance: Attendance will be taken each day, as required by the University Regulations. This policy may be found in the Undergraduate Catalog, and you should make yourself familiar with it. In particular, note that excessive unexcused absences are considered 10% of the total classes, which for this semester and class are three (3) class periods. According to the University Regulations, this may result in your being withdrawn from class by the instructor. This is not automatic however, so you should consult the instructor if you think you may have been withdrawn from class. Do not assume that you will be automatically withdrawn from class for non-attendance. Even if you are allowed to continue, please understand that your grade will suffer from lack of attendance. You will miss material that is only available in class, and classroom participation is crucial to your success in this class. In the event of an excused absence, you are responsible for providing acceptable documentation and making arrangements for making up for the lack of participation. Every student is responsible for anything covered in class, even if it is not in the text. This includes announcements of assignments or test dates, so if forced to miss class, be sure to contact the instructor and ask to be informed of those announcements.
· Disability: “If you are a qualified student with a disability seeking accommodations under the Americans with Disabilities Act, you are required to self-identify with the Office of Disability Services, Room 203, Student Union. No accommodations will be granted without documentation from the Office of Disability Services.”
· Student behavior/Classroom decorum: "Free discussion, inquiry, and expression is encouraged in this class. Classroom behavior that interferes with either (a) the instructor’s ability to conduct the class or (b) the ability of students to benefit from the instruction is not acceptable. Examples may include routinely entering class late or departing early; use of beepers, cellular telephones' or other electronic devices; repeatedly talking in class without being recognized; talking while others are speaking; or arguing in a way that is perceived as ‘crossing the civility line.’ In the event of a situation where a student legitimately needs to carry a beeper/cellular telephone to class, prior notice and approval by the instructor is required." Otherwise, ALL BEEPERS, CELLULAR TELEPHONES AND OTHER ELECTRONIC DEVICES MUST BE TURNED OFF BEFORE YOU ENTER THE CLASSROOM.
· Classroom behavior that is deemed inappropriate and cannot be resolved by the student and the faculty member may be referred to the Office of Judicial Affairs for administrative or disciplinary review as per the Code of Student Conduct, which may be found at http://www.selu.edu/Student Affairs/Handbook/
· Academic Integrity: “Students are expected to maintain the highest standards of academic integrity. Behavior that violates these standards is not acceptable. Examples are the use of unauthorized material, communication with fellow students during an examination, attempting to benefit from the work of another student and similar behavior that defeats the intent of an examination or other class work. Cheating on examinations, plagiarism, improper acknowledgment of sources in essays and the use of a single essay or paper in more than one course without permission are considered very serious offenses and shall be grounds for disciplinary action as outlined in the current General Catalogue.”
· “Students agree by taking this course that all required papers may be subject to submission for textual similarity to Turnitin.com for the detection of plagiarism. All submitted papers will be included as source documents in the Turnitin.com reference database solely for the purpose of detecting plagiarism of such papers. Use of the Turnitin.com service is subject to the terms and conditions of Use posted on the Turnitin.com website”
· Correspondence: Your Southeastern Louisiana University e-mail address MUST be used for all e-mail communication with faculty/administration/staff. Students are encouraged to check their Southeastern e-mail frequently for important communications from the university.
· University policy states that classrooms and labs are not a place for children. Students are not to bring their family members for day care or baby-sitting.
