Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Engineering mechanics tasks
Engineering mechanics tasks covered by this unit include, but are not limited to:
application of resultant loads and reactions on machines, support frames and beams
application of the torque and power required to drive translation screws and winding drums against inclined and vertically suspended loads subject to gravitation, acceleration and friction resistance loads
selecting a range of standard hardware, such as shafts, bolts and hooks, subject to plane axial or shear stresses and deformation limits
analysing bending and shear stresses in beams subject to static point and distributed loads
Motion
Motions described in this unit may be of constant velocity, constant acceleration or sinusoidal accelerations (e.g. sprung bodies). Other non-uniformly accelerated motions may be described for contrast only. This unit confines itself to 2-D plane motion
Appropriate licensed technical and professional assistance
Appropriate licensed technical and professional assistance may include:
technical support and advice relating to elements which have intrinsic dangers, such as:
high pressure
energised fluid vessels
high temperatures and heat energy capacity
wiring with high current control voltages above extra low voltage
professional support for technologies may include:
specialist electric motor drives and controllers
specialist materials, plastics, metal alloys and nano materials
special processes, foundry, alloy welding, heat treatment, sealing and fastening
WHS, regulatory requirements and enterprise procedures

WHS, regulatory requirements and enterprise procedures may include:
WHS Acts and regulations
relevant standards
codes of practice from Australian and overseas engineering and technical associations and societies
risk assessments
registration requirements
safe work practices
state and territory regulatory requirements
Analysis
Analysis may include:
static and dynamic analysis of loads
the stresses and deformations resulting
the transmitted power, torque and speed
graphical and mathematical methods and software options

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
A person who demonstrates competency in this unit must be able to apply principles of mechanics to machines, support frames, beams and related components to determine static and dynamic loads, stresses and deformations to contribute to the design and component selection process.
This includes working individually and as part of a team and recognising and complying with normal control procedures on engineering projects.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
determine parameters and context of tasks
apply WHS, regulatory requirements, risk management and organisational procedures
confirm personal functions and responsibilities
review sustainability implications, functions and features of devices, machines and systems
assess and apply engineering mechanics principles, including use of software basic analysis and graphics skills and techniques
ensure compatibility of units in calculations
report and document results.
Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job then a simulated working environment must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessment may be in conjunction with assessment of other units of competency where required.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
