Course Description: This course represents the second part of the traditional engineering mechanics static-dynamics course. The dynamics deals with accelerated motion of a body. There are many problems in engineering whose solutions require application of the principles of dynamics, from mechanical devices and industrial machinery to predictions of motions of artificial satellites or spacecraft.

This course is a basic course in many engineering curricula. The course has the objective to develop in the engineering student the ability to analyze any problem in dynamics in a simple and a logical manner and to apply to its solution a few, well-understood basic principles of mechanics.

Required texts:

Engineering Mechanics Dynamics, eight edition; R.C. Hibbeler

Learning tools, Progress evaluation and Requirements

Participation on each and every class is necessary to fully understand the material. The reading of your book is not going to be enough for you to consider as an accomplishment for this course.

· A set of problems designed to provide practice and illustrate the concepts will be assigned, twice a week. It will be due at the beginning of the next meeting/ lecture session

Each problem will be scored on a 0-20 points basis.

To be able to solve the problems you need to:

Ø Read the problem carefully and try to understand the principle which is applied;

Ø Draw any necessary diagrams, which can help you “see” the situation;

Ø Establish a coordinate system

Ø Establish the principle general mathematical formula you are going to use, write the formula ( do not put the numbers just yet);

Ø Solve the equations algebraically paying special attention to units and place the given data into your formula.

Ø Study the answer using technical judgement and common sense to determine if your solution is correct.

IMPORTANT NOTE

Students will have a folder in which he will place their homework.

· The material from this textbook has been divided into three units. There will be a unit test on or about the listed test date during our class period. Each of these will have a “ take-home” part. This will be issued about one week before the due date and will be “ do 5-6 problems from the textbook” and will be 70% of the test score. In class on the due date you will have the second part of test consisting in multiple choices questions or/ and short questions regarding the understanding of the theoretical principles covered in that unit. This will be the remaining 30% of your grade for each test.

INDIVIDUAL, INDEPENDENT WORK IS EXPECTED.

NO LATE SUBMISSION WILL BE ACCEPTED WITHOUT CONSIDERABLE SERIOUS REASONS. 20% will be counted down for each day you are late.

ABSENCE POLICY FOR QUIZZES AND EXAMINATIONS

There will be no make-up of missed homework assignment, regardless of the reason for the absence. If you are absent form the class when the homework is assigned, you are expected to obtain the problem from a classmate and hand it in at the required time. A missed homework assignment will be recorded as a zero grade.

3. Attendance at examinations is mandatory. Those with excused absences

will be able to make up the exam (once) at the scheduled date by your instructor. Permission to miss an examination must be obtained from the instructor prior to examination. Family emergency, University activity and health problems need to have written documentation. Those with unexcused absences will be given a zero grade for this portion of the course; the unexcused absence to the regular date of your exam will not give you the permission to come at the make up time scheduled for that particular test

Grading policy: SUMMARY: examinations 55%

assignments 45%

TOTAL POSSIBLE = 100%

GRADE ASSIGNMENTS:

85%<A<100%; 75%<B<85%; 65%<C<75%; 55%<D<65%; F<55%

CALCULATOR POLICY

Successful completion of this course requires your possession of a scientific calculator with at least the power of the Casio FX -300 series. You are expected to bring working scientific calculator to every class. If you do not already own such a calculator, a Casio fx-300 series calculator or an equivalent can be purchased at Wall-Mart for about $15. Of course, you may use as expensive a scientific calculator as you wish to purchase, provided it possesses the functions available on Casio fx-300 series.

Attendance Policy and Defined Excuses

Attendance is expected. Students are expected to participate fully in class discussions and in-group assignments. Show the instructor documentation for missing class for a university sponsored event as soon as possible in advance of the absence so that arrangements may be made for makeup. In case of illness or other unavoidable reason for missing, it is the responsibility of the student to contact the instructor within 24 hours and be able to document the reason for being absent. Absences for university sponsored events will not count as an absence in recording grades. In the case of illness and other unavoidable absences, only the first three verifiable ones that are reported to the instructor within 24 hours will be excused. Missing a class is not a legitimate excuse for turning in assignments late. Attendance at each class or discussion period will count one point and each absence that is not excused will count zero points.

Special Needs Statement

Students with special needs should contact the instructor to make appropriate arrangements.

Religious Beliefs Accommodation

Board of Regents policy states that students' sincerely held religious beliefs shall be reasonably accommodated with respect to scheduling all examinations and other academic requirements. Students must notify the instructor, within the first three weeks of the beginning of classes (within the first week of summer session and short courses) of the specific days or dates on which they will request accommodation from an examination or academic requirement. For additional information, please refer to the section of the University Bulletin and the Timetable titled Accommodation of Religious Beliefs.

Academic Misconduct

The University believes that academic honesty and integrity are fundamental to the mission of higher education and of the University of Wisconsin System. The University has a responsibility to promote academic honesty and integrity and to develop procedures to deal effectively with instances of academic dishonesty. Students are responsible for the honest completion and representation of their work, for the appropriate citation of sources, and for respect of others' academic endeavors. Students who violate these standards are subject to disciplinary action. URS Chapter 14 identifies procedures to be followed when a student is accused of academic misconduct. For additional information, please refer to the section in the Student Handbook titled, Student Academic Disciplinary Procedures.

Absence for University Sponsored Events

University policy adopted by Faculty Senate and the Whitewater Student Government states that students will not be academically penalized for missing class in order to participate in university sanctioned events. They will be provided an opportunity to make up any work that is missed; and if class attendance is a requirement, missing a class in order to participate in a university sanctioned event will not be counted as an absence. A university-sanctioned event is defined to be any intercollegiate athletic contest or other such event as determined by the Provost. Activity sponsors are responsible for obtaining the Provost's prior approval of an event as being university sanctioned and for providing an official list of participants. Students are responsible for notifying their instructors in advance of their participation in such events.

IMPORTANT INFORMATION YOU SHOULD KNOW

The University of Wisconsin – Whitewater is dedicated to a safe, supportive and non-discriminatory learning environment. It is the responsibility of all undergraduates and graduate students to familiarize themselves with University policies regarding Special Accommodations, Misconduct, Religious Beliefs Accommodation, Discrimination and Absence for University Sponsored Events. (For details please refer to the Undergraduate and Graduate Timetables; the “Rights and Responsibilities” section of the Undergraduate Bulletin; the Academic Requirements and Policies and the Facilities and Services sections of the Graduate Bulletin; and the “Student Academic Disciplinary Procedures” [UWS Chapter 14]; and the “Student Nonacademic Disciplinary Procedures” [UWS Chapter 17]).
