Office Hours: Wednesdays, 36 pm and by appointment TAS: Ms. Feruza Amirkulova, [email protected] Office Hours: 5pm 7pm on Thursdays in Engineering D115A Ms. Juan Ren, [email protected] Office Hours: 4pm 6pm on Tuesdays in Engineering D115 REQUIRED TEXT/WEBSITE Engineering Mechanics Dynamics & Mastering Engineering Package, 12/E, R.C. Hibbeler, Prentice Hall, 2007. http://www.masteringengineering.com LECTURES AND INFORMATION 3 hours of lectures per week. MW 12:001:20pm, SEC 117 or ARC 107 The lecture in SEC 117 (led by the instructor) will cover mostly theory and problem solving techniques. The lecture in ARC 107 (led by the TAs) will consist of solved example problems and discussion of problem solving techniques. For general class information: sakai.rutgers.edu: Engineering Mechanics: Dynamics For homework assignments and submissions: www.masteringengineering.com. You are to enroll in the course (ID: RUTGERSDYNAMICSROSSMANN) after you register at the website using the passcode that comes with your textbook or you have purchased separately. HOMEWORK Homework will be assigned on Wednesdays and be due before 11pm on the following Wednesday. No late homework will be accepted. No makeup homework will be allowed. All homework assignments are available online at http://www.masteringengineering.com. See course schedule for the due dates. Each student must submit the homework solution online. Homework will be graded online and the grade will be posted on our sakai course website. Only the best 10 (out of 12) HW scores will be counted. QUIZZES Four quizzes (40 min.) will be given in class throughout the semester. The quizzes are closed book and closed notes. No makeup quizzes will be given. The quizzes will begin at 12:40pm on the days listed in the course schedule. Class material covered on each of the quizzes will be announced in class prior to the exam. Your best 3 out of 4 quizzes will be counted towards your final grade. MIDTERM/FINAL EXAM The midterm and final exams are closed book and closed notes. You will be provided with a formula sheet at the time of the exam. The midterm will cover all material up to and including section 15.4. The final will be cumulative. Makeup exams will be given only to those with legitimate excusable absences (with written record). Makeup exams will be scheduled by the instructor.

COURSE OBJECTIVES At the conclusion of this course, student should be able to: 1. Draw the appropriate freebody diagram for each problem, including linear and rotational accelerations. 2. Readily and reliably perform dot and cross products on vectors. 3. Know the difference between kinematics problems and kinetics problems. 4. Identify the most direct approach to solving dynamics problems. 5. Solve both linear and rotational kinematics problems, using linear, planar and 3D solution techniques, where appropriate. 6. Solve kinetics problems by combining Newton's Law and kinematic equations, methodically accounting for all forces, and accelerations. 7. Solve kinetics problems using the principle of work & energy. 8. Solve kinetics problems using the principle of impulse & momentum. 9. Identify kinetics problems for which energy or momentum is conserved, and solve them appropriately. 10. Solve dynamics problems using both algebraic and vector techniques. HONOR CODE/ JOINT WORK I expect you to uphold an honor system: You may consult each other on the homework and projects. That means you are free to discuss the assignments and solution approaches, but it does not mean that you are free to copy anyone's exam, quiz, homework, or project. Any work turned in for this class must be your own work product and original effort.
