ENEM12009 - Structural Mechanics

General Information

Unit Synopsis

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.

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).

Assessment Overview

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 Tasks

Assessment Task Weighting
1. Written Assessment 20%
2. Written Assessment 20%
3. Written Assessment 20%
4. Written Assessment 0%
5. Examination 40%

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%).

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.

Source: Moodle site
Feedback
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.
Recommendation
Continue and improve.
Action Taken
More 3D printed models used as students learning tools.
Source: Moodle site
Feedback
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.
Recommendation
Continue and improve.
Action Taken
More 3D printed models used as students learning tools.
Source: Moodle site
Feedback
Some students thought the contents of the workbook were not clear. It is also not so clear how to pass the workbook.
Recommendation
The requirements and passing criteria will be rewritten to make it clearer.
Action Taken
They were rewritten and it is clear now.
Source: Moodle site
Feedback
Some students thought to put more example problems in lectures and tutorials.
Recommendation
Example problems will be included in each lecture for the next offering.
Action Taken
More example problems were employed in lectures and tutorials.
Source: Moodle site
Feedback
The feedback on assignment 3 was given late, not before the exam.
Recommendation
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.
Action Taken
It is on time in 2019.
Source: Students Moodle feedback and solicited student feedback
Feedback
The unit is focused on failure analysis and mechanical engineering thinking - helping students to do analysis and learn design concept. The unit is managed professionally - useful for students learning to make the independent learner.
Recommendation
Keep it up and improve further.
Action Taken
Nil.
Source: Students Moodle feedback
Feedback
The key aspect of the unit is the tutorial sessions: engaged delivery with step by step processes of solutions employing quizzes and open-ended questions for their learning.
Recommendation
Keep it up and employ more 3D printed models to enhance student learning.
Action Taken
Nil.
Source: Students Moodle feedback
Feedback
All assignments expanded students knowledge and they are linked to the contents of units. The questions of the assignments were crafted differently, not taken from the textbook.
Recommendation
Continue with these types of crafting style assignments. It can help to avoid contract cheating and enable students to be more confident learners.
Action Taken
Nil.
Source: Students Moodle feedback
Feedback
Students feedback suggest that feedback on assignments should be improved.
Recommendation
An assignment feedback template may be implemented in the next delivery to improve the feedback quality; the sessional staff can be benefitted more from this initiative.
Action Taken
Nil.
Source: Students Moodle feedback
Feedback
Students views on the timing of weekly lecture and tutorial are that a day gap between the lectures and tutorials is essential to avoid mental fatigue to digest a lot of information delivered.
Recommendation
It will be communicated to the timetable people.
Action Taken
Nil.
Unit learning Outcomes

On successful completion of this unit, you will be able to:

  1. Analyse the elastic behaviour of engineering structures and components and determine stresses, principal stresses, strains and deflections and the effects of impact loads
  2. Analyse stress and strain using experimental methods
  3. Explain theories of failure and apply failure analysis to structures and components
  4. Describe the nature of engineering assumptions and explain both the approaches used to deal with uncertainty and limitations of the validity of results
  5. Prepare professional, technical project documentation showing evaluation of uncertainties and results obtained
  6. Communicate, work and learn independently and collaboratively and communicate in a professional manner

Learning outcomes are linked to Engineers Australia Stage 1 Competencies and also discipline capabilities. You can find the mapping for this on the Engineering Undergraduate Course website.
