ENAM12002 - Mechanical Analysis

General Information

Unit Synopsis

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.

Important note: Students enrolled in a subsequent unit who failed their pre-requisite unit, should drop the subsequent unit before the census date or within 10 working days of Fail grade notification. Students who do not drop the unit in this timeframe cannot later drop the unit without academic and financial liability.

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 30%
2. Written Assessment 20%
3. Written Assessment 50%
4. Written Assessment 0%

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: Have your say
Feedback
The level of assessment problems can be improved.
Recommendation
It is a good suggestion. Earlier, a different cohort pointed out the high level of difficulty in the assessment problems. The questions were toned down in difficulty. Perhaps, there is scope of striking some middle ground here. The questions will be now more carefully examined and set to a more reasonable level.
Action Taken
The questions in each assignment will be revised to more practical ones of a reasonable level.
Source: Have your say
Feedback
More opportunities for interaction will be provided through zoom sessions.
Recommendation
Presently, there are few interactive sessions with the students. Some students have requested more frequent interactive sessions. This will be explored and fortnightly Zoom sessions will be held to help such students.
Action Taken
It is good idea. The unit profile will be revised to add fortnightly Zoom sessions.
Source: Student Survey
Feedback
Study guides were well presented, the lecturer was very quick to respond to questions and there was freedom to learn at your own pace.
Recommendation
Will continue

No live lectures or tutorials made it harder to get help on specific questions.
Recommendation
Weekly Zoom sessions will be set to carry out tutorials

This material is very difficult to learn. Associate Degree students do not do enough mathematics to follow the proofs in this unit
Recommendation
Unit content and prerequisites will be reviewed and modified as required

Unit learning Outcomes

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.
