Synopsis

A characteristic of mechanical engineering is that things move. Parts are subject to forces, causing them to accelerate. They impact on each other, the resulting impulses causing changes in momentum. Parts spin and must be balanced while gyroscopic forces operate. Vehicles in space are subject to gravitational fields and propulsive thrusts. Fluctuating forces cause vibrations that can have many modes that must be damped out.

The student of this advanced course must develop the ability to analyse all of these.
The ability to analyse comes with a cost. Motions, forces, moments and energy are all subject to mathematical equations, many of them of an advanced nature. In grasping the fundamentals, the student will come to grips with differential equations, vectors, operators, matrices and tensors. These skills are built up as understandable solutions to practical engineering problems, illustrated where possible by real-time simulations.

Objectives

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

  1. analyse the kinematics and kinetics of 3D rigid bodies;
  2. demonstrate an understanding of and apply equations to model the dynamic behaviours of engineering systems;
  3. construct and employ mathematical models of engineering systems to determine their dynamic characteristics;
  4. determine and assess the vibrational behaviour of systems of discrete bodies;
  5. demonstrate an understanding of and apply the principles of vibration theory, vibration measurements and control;
  6. apply software including commercially available packages such as MATLab to analyse the dynamics of engineering systems.

Notes
  1. This will be an open examination. Students will be provided further instruction regarding the exam by their course examiner via 精东传媒appDesk. The examination date will be available via UConnect when the official Alternate Assessment Schedule has been released.

Important assessment information

  1. Attendance requirements:
    It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration.

  2. Requirements for students to complete each assessment item satisfactorily:
    Due to COVID-19 the requirements for S2 2020 are:
    To satisfactorily complete an individual assessment item a student must achieve at least 50% of the marks for that item.

    Requirements after S2 2020:
    To satisfactorily complete an assessment item a student must achieve at least 50% of the marks or a grade of at least C-. Students do not have to satisfactorily complete each assessment item to be awarded a passing grade in this course. Refer to Statement 4 below for the requirements to receive a passing grade in this course.

  3. Penalties for late submission of required work:
    Students should refer to the Assessment Procedure (point 4.2.4)

  4. Requirements for student to be awarded a passing grade in the course:
    Due to COVID-19 the requirements for S2 2020 are:
    To be assured of receiving a passing grade a student must achieve at least 50% of the total weighted marks available for the course.

    Requirements after S2 2020:
    To be assured of receiving a passing grade a student must obtain at least 50% of the total weighted marks available for the course (i.e. the Primary Hurdle), and have satisfied the Secondary Hurdle (Supervised), i.e. the end of semester examination by achieving at least 40% of the weighted marks available for that assessment item.

    Supplementary assessment may be offered where a student has undertaken all of the required summative assessment items and has passed the Primary Hurdle but failed to satisfy the Secondary Hurdle (Supervised), or has satisfied the Secondary Hurdle (Supervised) but failed to achieve a passing Final Grade by 5% or less of the total weighted Marks.

    To be awarded a passing grade for a supplementary assessment item (if applicable), a student must achieve at least 50% of the available marks for the supplementary assessment item as per the Assessment Procedure (point 4.4.2).

  5. Method used to combine assessment results to attain final grade:
    The final grades for students will be assigned on the basis of the weighted aggregate of the marks (or grades) obtained for each of the summative assessment items in the course.

  6. Examination information:
    Due to COVID-19 the requirements for S2 2020 are:
    An Open Examination is one in which candidates may have access to any printed or written material and a calculator during the examination.

    Requirements after S2 2020:
    Candidates are allowed to bring only writing and drawing instruments into the Closed examination.

  7. Examination period when Deferred/Supplementary examinations will be held:
    Due to COVID-19 the requirements for S2 2020 are:
    The details regarding deferred/supplementary examinations will be communicated at a later date.

    Requirements after S2 2020:
    Any Deferred or Supplementary examinations for this course will be held during the next examination period.

  8. 精东传媒app Student Policies:
    Students should read the USQ policies: Definitions, Assessment and Student Academic Misconduct to avoid actions which might contravene 精东传媒app policies and practices. These policies can be found at .

Assessment notes
