Catalog Description:
Covers kinematics; motions of particles and rigid bodies and kinetics; force, mass
and acceleration; work and energy; and impulse and momentum. Newton's second
law is applied to the dynamics of particles and rigid bodies. Topics covered include
development and application of the conservation of energy; impulse and
momentum; and the conservation of momentum forms of the second law. Students
learn to solve problems requiring the application of combinations of dynamics
principles and to relate "real world" conditions to theoretical dynamic models and
their results. Prerequisites: GE 204. F, Sp.

Course Objectives:

The main objective of this course is to develop in the engineering student the ability
to analyze any problem in a simple and logical manner and to apply to its solution
a few, well understood, basic principles.
This course is an important building block in learning how to analyze and design
structures and machines using kinematics principles of particles and rigid bodies,
kinetics principles of particles and rigid bodies. Throughout the course, a basic
understanding of the principles of forces and accelerations, energy and
momentum will be acquired. Also, vibration theories will be introduced.
This course provides students a level of professional competency to pass E.I.T test,
and later to pass P.E. test and for their life-long study capability.
Students develop critical thinking process by applying analytical and computational
methods for solving problems

Outcome
Students can solve problems of rectilinear and curvilinear motion of particles and
rigid bodies, linear and angular momentum.
Students can solve problems of power and efficiency, impulse, impact , and other
problems of energy and momentum
Students understand pendulum problem and vibration of particle and rigid bodies
Student can solve FE type dynamics problems (EIT test) with the success ration of
80% or better

Grading; For example, if a test has maximum 10 points,
carefully because you can’t receive 10 points even if you have a
right answer when there is a small symbolic error or a wrong
statement,)
8 points; Clean and organized solution, but has minor mistakes
6 points; Solution is hard to read, unorganized; has minor mistakes
4 points; Solution is hard to read, unorganized, has major mistakes

Late entry of homework will not be accepted
The instructor will keep the original homework and test papers for one year. To make
sure I have all copies of your work, I will not keep record until the end of the
scores. Students must make electronic copies in CD-ROM for their student
portfolio. If students fail to submit CR-ROM copies, there will be 5% penalty.

Attendance: If any student could not attend class, it is student’s responsibility to inform the
instructor and catch up with the class materials. Student must submit the
reason of absence and a plan to make up the missed class materials to make
it an excused absence. Please remember that there are attendance points
such as ten points for zero absence, 7 points for one absence, and 4 points for
two absences.
.
Class participation: Students can be awarded maximum ten points by tutoring other
students and actively participating class workshops. Students should submit
a report describing tutoring activities (numbers, durations, subjects, etc) and
in-class activities for other students (e.g. solving on the board during
workshops).
Reading Assignment: Even though the instructor doesn’t expect that students could
understand all the topics by reading at home in advance, still students are
expected to read (at least scan) the assigned chapters before coming to
classes to be able to follow our schedule.

Learning Tools
Students must utilize the web-based learning center offered by the textbook
author (www.mhhe.com/beerjohnston7). Students should study tutorials,
Matlab computer solutions, software program, and Fundamentals of
Engineering (FE, or formerly known as EIT) exam questions provided at the
Website.

The instructor likes to have feedback from students during classes. Student
evaluations at the end of the semester are helpful but too late for the students to
have immediate benefit. The student advisory committee will report to the
instructor at least twice a month about the tempo of the lecture, adequacy of
homework, reading assignment, office hour, student forum, method of tests or
grading policies, or other suggestions. Students should elect committee members
and provide information.

Extra Work: Students are encouraged to do research works or application to industry
design. Students can turn in their extra work to improve their grades or
make up absence or homework grade. Copying from Web sites doesn’t
qualify for this.
If you need course adaptations or accommodations because of a disability, if you have
medical and/or safety concerns to share with me, or if you need special arrangements
in case the building must be evacuated, please make an appointment with me as-soon-
as possible.
