Hibbeler Pearson Prentice Hall ISBN: 0-13-141678-2 Course Description: The kinematics of particles is introduced with topics such as rectilinear motion and curvilinear motion. The kinetics of particles is covered utilizing Newton's Second Law, energy and impulsemomentum principles. Kinematics of rigid bodies is included and covers translational and rotational motions. Kinetics of rigid bodies is also covered for translation, rotation and general plane motion. Topics Dynamics of a Particle: Coordinate System Particle motion: Curvilinear Coordinates Work-Energy and Impulse & Momentum for a Particle Rigid Bodies: Force-Mass-Acceleration Rigid Bodies: Work-Energy Rigid Bodies: Impulse & Momentum Homework/Quizzes Homework will be assigned according to provided schedule. Modifications to the schedule may be announced in class, via e-mail or through the class website. You are required to read the textbook in addition to solving the homework problems. The homework will not be collected. About 10 quizzes will be given covering the class and homework material. Credit will be given for quizzes. There are NO make up quizzes. At the end of the semester the lowest quiz grade will be dropped. Methods of Evaluation Quizzes Exams 1 and 2 Final Exam 20% 50% (25% each) 30% Midterm Exams Tests will be conducted during class times. Tests will be closed book. A formula sheet will be provided by the instructor. This formula sheet is available on the webpage for your review. Final Exam The final exam will be comprehensive. A formula sheet will be provided by the instructor. This formula sheet is available on the webpage for your review. Communication Note that announcements may be made during class, via e-mail or through the webpage. Emails will be sent to the e-mail address you have registered with the university. Letter Grades A B C D F 90(+) – 100% 80(+) – 90(-)% 70(+) – 80(-)% 60(+) – 70(-)% Less than 60% Pledged work You may consult with your fellow students if you have difficulties with homework problems – in fact, discussion is encouraged. Each student is expected to fully comply with the Honor Code: NO CHEATING IN ANY WAY OR FORM. If a student is caught cheating, s/he will receive an AUTOMATIC F for the course. Moreover, if a student sees someone else cheating, s/he should REPORT the incident to the instructor. Plagiarism is of course considered cheating.
