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.

National Codes, Titles, Elements and Performance Criteria

 National Element Code & Title: EDX190B Analyse force systems (advanced) Element: 1. Solve problems using the laws of dry sliding friction. Performance Criteria: 1.1 Problems are solved using the laws of dry sliding friction for objects on horizontal and vertical planes1.2 Problems are solved using the laws of dry sliding friction that involve the use of moment equations Element: 10. Use Johnson or Euler equations to determine buckling loads Performance Criteria: 10.1 The column is analysed to determine whether the Johnson or Euler equation can be used10.2 End fixing conditions are analysed to determine the effective length10.3 The buckling load is calculated Element: 11. Determine the thermal stress in single members caused by restraint and changes in temperature Performance Criteria: 11.1 Calculations are carried out to determine thermal stress in simple members caused by full or partial restraint and changes in temperature Element: 2. Determine support reactions for determinate structures. Performance Criteria: 2.1 Free Body Diagrams  are drawn of loaded structures showing the support reactions2.2 The support with a reaction in a known direction is recognised and the direction shown on the Free Body Diagram2.3 Support reactions (magnitude and direction) are determined using the laws of equilibrium Element: 3. Determine the internal forces acting on members of a pin jointed truss. Performance Criteria: 3.1 A variety of recognised methods are used to determine the internal forces acting on all members of simple 2D pin-jointed truss3.2 Tension and compression members are differentiated Element: 4. Determine the pin reactions of a pin jointed frame. Performance Criteria: 4.1 The Method of Members is used to determine the forces acting on the pins of a simple 2D pin-jointed frame or machine Element: 5. Determine pin and support reactions for a simple noncoplanar non-concurrent force system Performance Criteria: 5.1 Given a range of simple 3D shaft or trapdoor systems, the magnitude of the components of the forces at supports, pins or hinges is determined Element: 6. Determine bolt sizes or number of bolts required for simple bolted connections. Performance Criteria: 6.1 The appropriate cross-sectional area from a standard bolt data table is used in calculations6.2 Calculations are completed to determine the size or number of bolts required for simple bolted connections Element: 7. Determine the nominal weld size or length of weld required on simple welded connections Performance Criteria: 7.1 Calculations are completed to determine the size and length of welds for simple welded connections subjected to direct shear only Element: 8. Determine wall thickness in thin walled cylinders subjected to pressure Performance Criteria: 8.1 The equations for hoop stress and longitudinal stress are used to calculate stresses in thin-walled vessels subject to pressure8.2 The equations for hoop stress and longitudinal stress are used to determine the required minimum wall thickness for thin walled vessels8.3 A factor of safety is applied in calculations involving thin walled vessels subject to pressure Element: 9. Calculate shaft size and angle of twist for simple circular shafts subject to torques Performance Criteria: 9.1 The torsional shear stress formula is used to calculate torsional shear stress and angle of twist in a circular shaft for a given torque load9.2 Torque distribution diagrams are sketched to determine maximum torque for shafts involving several power take-off points9.3 The torsional shear formula is used to calculate the nominal diameter of a simple circular shaft for a given torque load9.4 A shaft size is calculated for a simple shaft to meet a requirement for maximum stress or maximum angle of twist

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

The assessment matrix below refers to the topics shown in the teaching schedule. These topics encompass all of the elements shown above.
In keeping with the competency-based method of assessment, you must demonstrate competency in each element.

Disability Liaison Unit:
If you have a disability or long-term medical condition you should contact the DLU to seek advice and support.

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.
