Textbook: Hibbeler, R.C., Dynamics, Ninth Edition, Prentice-Hall, 2001.

Catalog Description:

Kinematics and kinetics of particles. Rigid bodies in translation, rotation and plane motion. Includes impulse-momentum and work-energy methods. Introduction to vibrations.

Prerequisites: ME256 or ME253, PHYS 205, PHYS 206.

Objectives: Most mechanical systems include parts and assemblies in motion. The study of the relationship between load and motion and of methods to analyze and predict their mutual effects is covered in this fundamental course.

Topics: Kinematics of a particle along a straight line.

Kinematics of a particle along a curve. Angular motion.

Relative motion.

Kinetics of a particle. Newton's second law.

Center of mass. Its kinetics.

Energy methods. Principle of work and energy. Power.

Conservation of energy.

Momentum methods. Principle of impulse and momentum.

Linear and angular momentum.

*****************************************************************

Rigid body kinematics.

Rotating coordinate systems.

Kinetics of rigid bodies: motion, momentum. Moments of inertia.

Energy methods.

Momentum methods.

*****************************************************************

Vibrations. Free and forced. Damping.

Grading: Homework (20%)

Quizzes (30%)

Midterm exam (20%) [Wed., 20 Feb., 2002]

Final exam (30%) [Mon., 22 Apr., 2002, 5 p.m.]

Quizzes will be given weekly. As the course proceeds, homework problems from the textbook will be assigned. Homework will be collected at the beginning of the Monday class. Randomly selected, two homework problems will be graded. One of the homework problems from the previous two weeks will be given as a 15-minute quiz at the end of the Wednesday lecture. The use of notes and books is not allowed. Essential equations will be provided.

In the midterm exam three problems will be assigned, including the lecture material covered up to the previous week. The use of the course textbook is allowed.

In the final exam three problems will be assigned, covering the entire semester course material. The use of the course textbook is allowed.

A=90%- ; BA=85%- ; B=80%- ; CB=75%- ; C=70%- ; DC=65%- ; D=60%- ; E=below 60%.

Notes: | Best learning is achieved by solving problems and asking questions. Do both !

| Dynamics is a science based course, but it has direct applications in engineering. Explore the applications to comprehend (and enjoy) the science.

| Grades are not assigned by the course instructor. They are gained by the student and only recorded and calculated by the instructor.
