Unit of Study Aims/Goals:


Course Objectives

Students should:


Understand the basic concepts and methods emp
loyed in describing the dynamics of
rigid bodies, and develop the skill of solving two and three dimensional dynamics
problems, and be able to analysis the vibrations of systems with one degree of freedom.


The relationship of this Unit to previous UoS
:

This is a second course in engineering kinematics and dynamics, it is based on
engineering mechanics 1530, which is a pre
-
requisite for this UoS, the students should
have also passed a first year courses in mathematics and vector algebra.



The relatio
nship to subsequent UoS:


The knowledge gained in this unit of study is also used in other engineering subjects
such as MECH 350 System Dynamics and control, Mechanical Design 1, Mechanical
2A and Mechanical Design 2B.

.


Rel
ationship between this UoS and University generic attributes:


This unit of study is aimed at developing the students generic attributes in the following
areas:

-

angular impulse and momentum to solve rigid
-
body planar
kinetics

Learning Situations


Lectures

There are three lectures each week. Students are exp
ected to

read the relevant

sections
prior to the lectures. During the lectures basic material will be presented with an
emphasis on explaining the more difficult concepts, and presenting worked solutions of
sample problems.

The tutors will assist you with
your understanding of the knowledge needed to solve the
problems,
they will not solve the problems for you
.
Solutions to the problems will be made available from time
to time.


Laboratory reports to be subm
itted to the lab demonstrator
two weeks after the laboratory session.

NOTE: Late submissions will be penalized 10% of full mark for
every day or part thereof that the assignment and or lab report
is late
(unless medical certificate etc is sighted).





Assessment:



Assessment marks for assignments and examination will be based upon:
