Engineering Mechanics Dynamics, 10th Edition

R.C. 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 impulse-momentum 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.

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.
