ENAM12006 - Mechanical Component Selection

General Information

Unit Synopsis

This unit introduces you to the relationship between material properties, structure, and functional performance of mechanical components such as gears, shafts, bearings, fasteners etc. You will apply material selection to determine the load for individual machine elements. Subsequently, you will learn to determine the shape and sizes of components by the way of comprehensive analysis, estimation, and selection. You will select and specify common mechanical components like drive line, shafts, axles, gears, bearings, mechanical fasteners, and other relevant parts and modules complying with the relevant standards and codes. You will specify fits and tolerances, and finishes required for mechanical components.

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 40%
2. Written Assessment 50%
3. Online Quiz(zes) 10%

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: Students
Feedback
Avoid using multiple textbooks.
Recommendation
Stay with the prescribed textbook but assignment and exercise questions should be taken from the textbook and other books.
Action Taken
Yes, the new version of Shigley's Mechanical Engineering Design (SI Version)11th edn (2021) has been adopted.
Source: Students
Feedback
Improve Moodle navigation.
Recommendation
Unit Moodle site should be built up as new with updated materials, older materials must not be mixed up with new ones.
Action Taken
Yes, they have been done.
Source: Students
Feedback
A large amount of topics and materials covered.
Recommendation
For AD Engineering students, it is suggested to reconsider the unit schedule and content and reduce the number of topics in respect of this offering. Some students appreciated the wider scope of learning.
Action Taken
The number of topics was kept because the selection of each mechanical component is very important, and its procedure and calculation are relatively independent.
Source: Students
Feedback
Elaborated feedback on assignments appreciated.
Recommendation
Keep providing elaborate feedback and suggestions for improvement in assignments.
Action Taken
Yes, will continue. Some improvements in assignments have been made, e.g., some assignment problems were changed.
Source: Students
Feedback
Delayed assessment item return.
Recommendation
Return marked assessment items within two weeks.
Action Taken
Yes, it has been done within one week.
Source: Student feedback
Feedback
The extension of students' professional knowledge helped them relate to the topics easily.
Recommendation
The topics will be kept and updated.
Action Taken
Nil.

Feedback
Audio quality in video recordings was poor and difficult to follow.
Recommendation
Zoom session will be moved to the room with AV Full.
Action Taken
Nil.
Source: Student feedback
Feedback
Textbook extracts from outside resources were difficult to follow in the study guides, underutilising the prescribed textbook for the course.
Recommendation
Lecturing notes were mainly based on the prescribed textbooks. But, some workbook questions were from outside resources. They will be improved and more questions will be from the prescribed textbooks.
Action Taken
Nil.
Source: Student feedback
Feedback
A corrected assignment paper from each assignment posted shortly after the marking of each would be beneficial.
Recommendation
In this term, for each week workbook questions, a corrected paper was uploaded into the moodle site each week. Similar work will be done for the assignment questions.
Action Taken
Nil.
