__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.
