Overview
In this unit, you will study the behaviour of solid bodies under different loadings by applying basic stress analysis principles and the introductory knowledge of engineering materials. You will gain in-depth understanding of the concepts of continuum stress, strain and deflection; analyse the response of mechanical components to axial, transverse, torsional, bending and buckling loads in the linear elastic regime. You will apply the theory of generalised Hooke’s law to design pressure vessels and similar thin walled structures. You will perform calculations concerned with the mechanical properties of materials and conceptually design different mechanical components and structures based on strength, stiffness and stability. You will acquire the skills and knowledge required to develop analytical techniques that are used to solve a wide range of linear stress/strain problems in engineering practice.

Offerings For Term 1 - 2019
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.

Feedback, Recommendations and Responses
Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.
Feedback from Moodle site
Students think ENEM12009 was fantastic this term. Unit was interesting and engaging. It was well run with great depth in content and well aligned assignments.
Continue and improve.
Feedback from Moodle site
The students think that the way the tutorials are run are very inclusive with detailed explanations - this is a very efficient way to complete the teaching, creates consistency across the campuses.
Continue and improve.
Feedback from Moodle site
Some students thought the contents of the workbook were not clear. It is also not so clear how to pass the workbook.
The requirements and passing criteria will be rewritten to make it clearer.
Feedback from Moodle site
Some students thought to put more example problems in lectures and tutorials.
Example problems will be included in each lecture for the next offering.
Feedback from Moodle site
The feedback on assignment 3 was given late, not before the exam.
The due date of assignment 3 was Friday week 12. The exam was within the two weeks return policy. Also because of extension, it was not possible to provide feedback before the exam date. I will put more care about extensions to provide feedback of assignment 3 quickly. However, the exam date can be within a week.

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.
What can you do to act with integrity?
