Course details
and aims
Units of
credit
This is
a 6 unit
-
of
-
credit (UoC) course
and involves 6 hours per week (h/w) of face
-
to
-
face contact.
Y
ou should aim to spend not less than about 10 h/w on this course,
that is,
an additional 4 h/w of
your own time. This
time
should be spent in mak
ing sure that you understand the lecture material,
further reading about the course material, completing the
on
-
course assessments
, and revising and
learning for the
quizzes and final
examination.
This course is a sequel to MMAN1300 Engineering Mechanics
1
. In MMAN1300, you
learned
about
S
tatics
-
the equilibrium of bodies under the action of forces
,
and
D
ynamics
-
the motion of
particles
and rigid bodies
.
This course covers engineering mechanics and mechanical vibrations. Part of the emphases of this
cou
rse is the
plane dynamics of rigid bodies and practical applications
. Another part of the course
aims on building your understanding of
mechanical vibrations
. You will develop an understanding
of the concept of vibration and the main components of vibrator
y systems. This course constitutes
an important component of the basic engineering sciences.
This course is a prerequisite for
MECH4100
Mechanical Design
and MECH4320
Engineering
Mechanics 3
.

Rationale
f
or inclusion of content and teaching approach
This course is included to
give you the tools necessary to analyse the motion of rigid bodies,
forces/moments to generate the motion and the fundamentals of vibration analy
sis
.
Lecture material
and tutorial exercises have been carefully selected and a wide range of asse
ssment activities will be
given to support the learning and teaching approach
.
Teaching strategies
The teaching approaches that will be used include:
Prese
ntation of the material (derivations and examples) in lectures
Tutorials to help students to understand and solve problems
Laboratory experiments
to assist in understanding the fundamentals taught in lectures
Series of quizzes which require students to
reg
ularly study their lecture material.

Academic Honesty
a
nd Plagiarism
What is Plagiarism?
Plagiarism is the presentation of the thoughts or work of another as one’s own.* Examples include:
direct duplication of the thoughts or work o
f another, including by copying material, ideas or
concepts from a book, article, report or other written document (whether published or
unpublished), composition, artwork, design, drawing, circuitry, computer program or software,
web site, Internet, other
electronic resource, or another person’s assignment without
appropriate acknowledgement;
paraphrasing another person’s work with very minor changes keeping the meaning, form
and/or progression of ideas of the original;
piecing together sections of the wor
k of others into a new whole;
presenting an assessment item as independent work when it has been produced in whole or
part in collusion with other people, for example, another student or a tutor; and
claiming credit for a proportion a work contributed to a
group assessment item that is greater
than that actually contributed.†
For the purposes of this policy, submitting an assessment item that has already been submitted for
academic credit elsewhere may be considered plagiarism.
Knowingly permitting your
work to be copied by another student may also be considered to be
plagiarism.
Note that an assessment item produced in oral, not written, form, or involving live presentation,
may similarly contain plagiarised material.
The inclusion of the thoughts or w
ork of another with attribution appropriate to the academic
discipline does
not
amount to plagiarism.
The Learning Centre website is main repository for resources for staff and students on plagiarism
and academic honesty. These resources can be located v
ia:
www.lc.unsw.edu.au/plagiarism
The Learning Centre also provides substantial educational written materials, workshops, and
tutorials to aid students, for example, in:
correct referencing practices
;
paraphrasing, summarising, essay writing, and time management;
appropriate use of, and attribution for, a range of materials including text, images, formulae and
concepts.
Individual assistance is available on request from The Learning Centre.
Students
are also reminded that careful time management is an important part of study and one of
the identified causes of plagiarism is poor time management. Students should allow sufficient time
for research, drafting, and the proper referencing of sources in pr
eparing all assessment items.
* Based on that proposed to the University of Newcastle by the St James Ethics Centre.

Course evaluation and development
Feedback on the course is gathered periodi
cally using various means, including the Course and
Teaching Evaluation and Improvement (CATEI) process, informal discussion in the final tutorial
class for the course, and the School’s Student/Staff meetings. Your feedback is taken seriously, and
continua
l improvements are made to the course based, in part, on such feedback.
In this course, recent improvements include restructuring the course contents and continuously
improving the dynamics part of the course.
Administrative matters
Information about e
ach of the following matters is presented in a School handout,
Administrative
Matters for All Courses
, available from the
School website
.
It is essential that you obtain a copy, read it carefully and become familiar with the information, as
it applies to
this course and to each of the other courses in which you are enrolled.
Expectations of students (including attendance at lectures and tutorials/laboratory
classes/seminars; and computer use, for example, in the use of email and online discussion
forums)

Equity and disability
Students who have a disability that requires some adjustment in their teaching or learning
environment are encouraged to discuss their study needs with the course convenor prior to, or at
the commencement of, their course
, or with the Equity Officer (Disability) in the Student Equity
and Disabilities Unit (SEADU) by phone on 9385
4734, email seadu@unsw.edu.au or via the
website
http://www.studentequity.unsw.edu.au
The office is located on the Ground Floor of the Goodsell
building (F20).
Issues to be discussed may include access to materials, signers or note
-
takers, the provision of
services and additional exam and assessment arrangements. Early notification is essential to
enable any necessary adjustments to be made.
