General Information

Overview

This unit introduces students to the analysis of the behaviour of objects in motion. You will be able to explain the motion of objects and solve problems involving objects experiencing constant linear and angular acceleration, and constant force and torque; and apply principles of conservation of momentum and energy to solve problems involving moving objects and simple machines. You will be able to solve problems involving friction, kinematics and dynamics, and oscillatory motion, forced vibration and resonance. You will be able to analyse static and dynamic balance of shafts and determine bearing reactions. Students are required to develop a capacity to work and communicate ethically and professionally, as individuals and in teams, to investigate and solve problems and present solutions professionally.

Assessment Grading

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%). Consult the University’s Grades and Results Policy for more details of interim results and final grades.

Assessment Title
Workbook

Task Description

The workbook provides a record and detailed diary of your learning and completed activities throughout the course. Preparation of a workbook should be understood as a good study technique. It also provides evidence that you have adequately studied the whole course and achieved the course learning outcomes. It is worthwhile doing a good attempt at the workbook as, if at the end of the course you are on the borderline between two final grades the workbook can be used to determine if the higher grade should be awarded.

A handwritten workbook is most appropriate and most time effective as the course involves many equations and diagrams. It is much quicker to write and sketch freehand. The handwritten workbook can be submitted electronically after scanning all the pages.The presentation of the workbook is not as crucial as an assignment as it is recognised you will make mistakes during your learning. Rough sketches and partial attempts/re-attempts of questions are acceptable and may add to your grade. The start of each section of work should be dated and all pages should be numbered. It should be prepared week by week, not at the end of the term. Show rough attempts at problems including failures and fixes, brainstorming, draft notes and developing ideas. In the workbook students must record:

  • Tutorials of each week and other problems/activities given in the Moodle

In the workbook students may also record:

  • study notes taken while studying textbooks and course resources
  • personal study summaries of key concepts
  • notes, sketches/ drawings

Assessment Criteria

Workbook activities guidelines:

Workbook activities are set for each week and are detailed in the Moodle.

As mentioned in the task description the presentation and accuracy of results of the workbook activities are not as crucial as an assignment as it is recognised you will make mistakes during your learning. Rough sketches and partial attempts/re-attempts of questions are acceptable and may add to your grade. Workbook activities are seen as ways to stimulate your own learning rather than final work you would submit to a colleague. However there should be some attempt to set out and document your work to show your understanding. Set out and document the activities in a way you could revisit them at a later date if required. The following repeated assignment criteria will help guide the layout of your workbook activities but should not be viewed as rigid.

Accuracy and correct results

• Correct application of mathematics.

• Answers clearly identified (please underline or highlight answers)

• Correct results

Evidence of correct procedures

• All necessary steps in the analysis are clearly shown. 

• Clear presentation of mathematical working linking the given details of the problem to the results obtained.

• Indication of the equations used when using spreadsheets (eg Microsoft Excel) or other software

• Evidence of checking results (mathematical, graphical, logic-common sense)

Evidence of understanding of the topic

• Explanation of any assumptions made

• Explanation of choices made in the analysis (why is this procedure is required)

• Interpretation of results, eg limitations, direction of vectors

Professional presentation

• The work is clearly identified (problem, date)

• Clear statement of each problem and its details and requirements

• Logical layout of analysis

• Clear statement of equations and theory used

• Appropriate use of diagrams, clear diagrams, adequately labelled

• Correct use of terminology, conventions

• Clear English in the explanation of procedure and interpretation of results

• Referencing of authoritative sources of equations and data

Academic Integrity Statement

As a CQUniversity student you are expected to act honestly in all aspects of your academic work.

Any assessable work undertaken or submitted for review or assessment must be your own work. Assessable work is any type of work you do to meet the assessment requirements in the unit, including draft work submitted for review and feedback and final work to be assessed.

When you use the ideas, words or data of others in your assessment, you must thoroughly and clearly acknowledge the source of this information by using the correct referencing style for your unit. Using others’ work without proper acknowledgement may be considered a form of intellectual dishonesty.

Participating honestly, respectfully, responsibly, and fairly in your university study ensures the CQUniversity qualification you earn will be valued as a true indication of your individual academic achievement and will continue to receive the respect and recognition it deserves.

As a student, you are responsible for reading and following CQUniversity’s policies, including the Student Academic Integrity Policy and Procedure. This policy sets out CQUniversity’s expectations of you to act with integrity, examples of academic integrity breaches to avoid, the processes used to address alleged breaches of academic integrity, and potential penalties.

What is a breach of academic integrity?

A breach of academic integrity includes but is not limited to plagiarism, self-plagiarism, collusion, cheating, contract cheating, and academic misconduct. The Student Academic Integrity Policy and Procedure defines what these terms mean and gives examples.

Why is academic integrity important?

A breach of academic integrity may result in one or more penalties, including suspension or even expulsion from the University. It can also have negative implications for student visas and future enrolment at CQUniversity or elsewhere. Students who engage in contract cheating also risk being blackmailed by contract cheating services.

Where can I get assistance?

For academic advice and guidance, the Academic Learning Centre (ALC) can support you in becoming confident in completing assessments with integrity and of high standard.
