ENAM12002 - Mechanical Analysis
Term 1 - 2017


All details in this unit profile for ENAM12002 have been officially approved by CQUniversity and represent a learning partnership between the University and you (our student). The information will not be changed unless absolutely necessary and any change will be clearly indicated by an approved correction included in the profile.

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.

Assessment Overview

Assessment Task Weighting
1. Written Assessment 30%
2. Written Assessment 20%
3. Written Assessment 50%
4. Written Assessment Pass/Fail

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 Procedures 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 Source Recommendation
Assignments are too difficult and are different from tutorial questions. Students have your say feedback Assignment task difficulty will be reviewed in line with associate diploma level graduate attributes. Assignments are designed to be different in nature to the tutorial questions to test the students understanding and their ability to apply the material in the course. Tutorial questions are designed for learning while assignments are designed for assessment. Will investigate adding some challenging tutorial questions that are more similar to assignment tasks so students can see what is expected for the assignments.
Some material overlap due to changes in Engineering programs Teaching staff reflection Review course material and ensure it is inline with course learning outcomes and has minimal overlap with other courses in the program.
Students not aware of e-books available Teaching staff reflection Provide links to CQU library's e-books that may be of help to students enrolled in the course.
Weekly reflections are extra work Students have your say feedback Will highlight to students that reflections should not take any more than 5 minutes per week.
On successful completion of this unit, you will be able to:
  1. Explain the basic concepts and principles of engineering mechanics
  2. Explain how engineering structures and components carry and transmit loads
  3. Analyse and determine: o Properties of plane cross sections o Forces acting in members of structures and assemblies in static equilibrium o Normal stress and strain in members and components in static equilibrium o Deflection of simple beams and trusses o Stresses in circular shafts o Principle stresses and maximum shear stresses using Mohr's circle o Buckling behaviour of columns
  4. Analyse failure of structures and components and determine fatigue lives of components
  5. Explain the nature of engineering assumptions and explain commonly made assumptions and consequent limitations of the validity of analyses based on such assumptions
  6. Communicate professionally and provide evidence of personal reflection on, and critical assessment of, team contributions and professional development
  7. Formulate and solve problems and record and communicate clearly and professionally the approach used to solve problems and the reasons for adopting such approaches to problems

The Learning Outcomes for this unit are linked with Engineers Australia's Stage 1 Competency Standard for Engineering Associates.

4 Written Assessment

Assessment Title Workbook
Task Description

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.

Assessment Due Date Exam Week Monday (12-Jun-2017) 05:00 PM AEST
Return Date to Students The workbook will be returned after the CQU Certification of Grades.
Weighting Pass/Fail
Assessment Criteria

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.

Accuracy and correct results

• Correct application of maths and arithmetic

• Answers clearly identified (please underline or highlight answers)

• Correct results

Evidence of correct procedures

• All necessary steps in analysis are present

• Clear presentation of mathematical and arithmetical 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 (job) is clearly identified (problem, date, analyst)

• 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

Conditions Minimum mark or grade - Successful completion of this assessment is a requirement for passing this course.
