SYNOPSIS:

The  application of the principles of Mechanics is abound in our daily
life.  Buildings  and  bridges are designed to  operate  under  normal
conditions  with  the  help  of  the  principles  of  Statics.   Under
extraordinary  conditions such as earthquake or high wind  speed,  the
design  is  governed by the principles of Dynamics (loading conditions
vary  significantly  with  time). Mechanical  systems  are  inherently
dynamic.  Moving parts exist in many products and equipment  :  simple
household  electrical  appliances,  office  equipment,  cars,  robots,
production  factories, mining, construction, agricultural machineries,
ships, aeroplanes and spacecrafts, etc. Knowledge of dynamics plays an
essential  role  in the design and analysis of any of  these  systems.
Apart from pure mechanical functionalities, modern systems incorporate
more  robust and accurate control with the help of electronic devices.
Flexible  and intelligent systems such as robots, computer  controlled
factories, autonomous vehicles are now common. These achievements  are
possible  because  very  detailed  and  accurate  system  dynamics  is
understood and advanced electronics and control are available.

This  advanced  course covers the formulation of vector mechanics  for
general  three dimensional systems of rigid bodies and the  theory  of
vibration and its applications. The principles and methods covered are
essential to the understanding of mechanical systems.

OBJECTIVES:

On successful completion of this course students should be
able to:

1. Understand the fundamental physical postulates of the theory
   of Newtonian Mechanics;
   
2. Understand the relevant mathematical foundation for Newtonian
   Mechanics;
   
3. Understand the principles of 3D kinematics and apply those
   principles to the analysis of 3D mechanical systems such as
   articulated robots;
   
4. Understand physical singularities and recognise their
   mathematical manifestation in inverse kinematics;
   
5. Understand Hamilton's Principle and apply Lagrange's
   equations;
   
6. Understand the physical concept of inertia and apply Newton's
   first law;
   
7. Understand the physical concept of mass and force and apply
   Newton's second law;
   
8. Understand the concept of energy and momentum and make use of
   the associated laws of conservation;
   
9. Understand and apply Newton's third law and law of universal
   gravitation;
   
10. Apply basic equations of motion derived from the fundamental
    principles;
    
11. Model, formulate and solve problems in 3D kinematics and
    kinetics of rigid bodies;
    
12. Understand and apply the principles of vibration theory,
    vibration measurements and control;
    
13. Understand the process of and carry out discrete modelling of
    vibratory continuous systems;
    
14. Determine the vibrational behaviour of systems of discrete
    bodies having two or more degrees of freedom, with or without
    viscous damping;
    
15. Understand the limitation of closed form analytical methods
    and be aware of and appreciate the use of computer discrete
    modelling tools;
    
16. Appreciate important phenomena such as dynamic imbalance and
    resonance and explain these phenomena mathematically;
    
17. Develop and write simple computer programs for the solution of
    certain problems in Mechanics.

OTHER REQUIREMENTS:

1    To  satisfactorily complete each of the assignments students must
     normally  obtain  at least half of the marks available  for  each
     assignment.
2    To  satisfactorily  complete  the  examinations  in  the  course,
     students  must  normally  obtain  at  least  half  of  the  marks
     available for each examination.
3    To receive a passing grade in this course a student must normally
     attempt  all of the assessments and achieve at least 50%  of  the

     to  provide  proof  of  the  submit date,  if  requested  by  the
     Examiner.

     assignment will apply for each working day late.
10   In  the event that a due date for an assignment falls on a  local
     public  holiday  in their area, such as a Show holiday,  the  due
     date  for  the assignment will be the next day. Students  are  to
     note  on the assignment cover the date of the public holiday  for

     reasons,  are unable to complete an assignment or to sit  for  an
     examination  at  the  scheduled  time  may  apply  to  defer   an
     assessment  in  a course. Such a request must be  accompanied  by
     appropriate  supporting  documentation.  One  of  the   following
     temporary  grades  may  be  awarded IDS  (Incomplete  -  Deferred
     Examination;  IDM (Incomplete Deferred Make-up; IDSM  (Incomplete
     Deferred Examination and Make-up).
