Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

EDX130B – Use technical mathematics (basic)
EDX140B – Use technical mathematics (advanced)
EDX100B – Analyse force systems (basic)

Course Description

This unit covers the competency to extend basic skills and knowledge in calculating forces, moments and stresses to AQF level 5. It brings the level of competency in force and stress analysis to that needed to commence design calculations in either the mechanical or structural field using Australian and/or ISO Design Standards.

Overview of Assessment

Assessment are conducted in both theoretical and practical aspects of the course according to the performance criteria set out in the National Training Package. Students are required to undertake summative assessments that bring together knowledge and skills. To successfully complete this course you will be required to demonstrate competency in each assessment tasks detailed under the Assessment Task Section.

Your assessment for this course will be marked using the following table:

NYC (<50%) Not Yet Competent

CAG (50-59%) Competent - Pass

CC (60-69%) Competent - Credit

CDI (70-79%) Competent - Distinction

CHD (80-100%) Competent - High Distinction


Assessment Tasks

This is a competency-based course and competency must be demonstrated for each element (shown above) to achieve competency for the course.
The elements and performance criteria are contained within the topics as listed in the teaching schedule on the BlackBoard.
Each topic will be assessed using the form of assessment and weighting shown below.
Please note that the topics listed in the assessment matrix below refer to the topics in the learning guide and teaching schedule and do not refer to the elements shown above.
Short quizzes will be held during classes to provide student feedback but these will not contribute towards formal assessment.

Late submission:
If you require an extension for 7 calendar days or less (from the original due date) you must complete and lodge an Application for Extension of Submittable Work (7 Calendar Days or less) form and lodge it with the Senior Educator/ Program Manager.
The application must be lodged no later than one working day before the official due date. The student will be notified within no more than 2 working days of the date of lodgment as to whether the extension has been granted.

If you require an extension of more than 7 calendar days (from the original due date) you must lodge an Application for Special Consideration form under the provisions of the Special Consideration Policy, preferably prior to, but no later than 2 working days after the official due date.

Assignments submitted late without approval of an extension will not be accepted nor marked.
