Overview
This unit introduces students to key concepts and principles of mechanical analysis. They explain how engineering structures and components carry and transmit loads, and analyse and determine properties of sections, forces in structures and assemblies, stress and strain in members and components, deflections, stresses in circular shafts, principle stresses and buckling of columns. Students analyse mechanical failures, determine fatigue life of components, and explain common assumptions made in analysis, their consequences and validity. Students are required to show they work productively, both individually and collaboratively, to solve problems, and document and communicate their work clearly in a professional manner.

Attendance Requirements
All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).
Recommended Student Time Commitment
Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Overview
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.

4 Written Assessment
This task is in two parts:
1) Weekly reflection:
A weekly reflection on your learning is required to be posted on the moodle course site. This is to include one sentence for each of the following questions. (Directions on how to post your reflections will be provided on the moodle course site.)
a. What did you learn during the past week?
b. How did you learn it?
c. How do you think you could apply it, either now or later in your career?
d. What did you find hard to understand?
2) Workbook:
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 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 border line between two final grades the workbook can be used to determine if the higher grade should be awarded.
The Workbook is best handwritten and then scanned and submitted electronically. 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 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 term. Show rough attempts at problems including failures and fixes, brainstorming, draft notes and developing ideas.
In the Workbook students must record:
- workbook activities you are asked to complete in the course notes
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
- initial attempts of assignment tasks
Workbook submission
- A Workbook progress submission is required 1pm Monday Week 5. Just submit your workbook to date to enable the teaching team to provide some feedback to let you know how you are going on this task.
- The whole Workbook is due at the end of the term, the due date is shown in the course profile.
Exam Week Monday (11 June 2018) 5:00 pm AEST
The workbook will be returned after the CQU Certification of Grades.
To pass this assessment you must:
- make a legitimate attempt of at least 50% of the Workbook activities for each topic in the course notes.
- submit weekly reflections on the moodle course site. (To provide flexibility you are permitted to submit your reflections 1 week late past the due date to enable those on 7 or 10 day rosters to submit. One week after the reflection due date you will not be able to submit to that week so please add your late reflection in the following week's reflection and label it accordingly ie 'Week 4 reflection'. If you work ahead, feel free to submit reflections in that learning week's reflection submission activity.)
Workbook activities guidelines:
Workbook activities are set for each Topic and are detailed in the Course Study Guide. All workbook activities have a brief solution provided so that students can check their results. Do not copy the solutions provided and submit as your own work. The solutions provided are only basic and should not be seen as a complete solution. I suggest you first attempt the questions without looking at the solutions. If having difficulty, work through the provided solution and then re-attempt the question without looking at the solution. If still having difficulty you are encouraged to scan your work and post it on the moodle course website Q&A forum.
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.

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.
