This unit best to be combined with MEM09011B Engineering Design Concepts

Select something (plant, product, project, system) to assess (mechanical design or assessment of changes).

This can be achieved either by RPL of a prior or current work-related project, or by undertaking a new project to fulfil this unit. Group project work is permitted.

Assessment is by a written REPORT, fulfilling all criteria according to Elements of Competency and Performance Criteria


For example report see the following link. A simple design study on modifiactions of a wheelbarrow.

Engineering Design Concepts: Chapter 7

The technical content of this example (force analysis) IS required in this unit. Analysis may involve any of the engineering physics areas, such as engineering mechanics (forces, stresses, motions) and also fluid mechanics, thermo etc.

ASSESSMENT

(*CAUTION: This subject contains two unofficial pre-requisites: MEM30005A Forces and MEM30006A Stresses. MEM30005A must be done prior (pre-requisite), but MEM30006A can be done concurrently (co-requisite) Assessment is a combination of multiple choice tests, written tests, and submitted reports (print/email).

  • Lab Reports: Specification for lab reports. (Including error analysis where required)
  • Project Reports: Specification for project reports.
  • TESTER tasks: Computer based learning and assessment using the TESTER program.
    Procedures and rules. For most computer-based assessments, homework must be presented before Tester (exam mode) can be attempted.  In some cases, certain programs (e.g. Excel) are excluded from running with Tester during an exam. 


Pre-Requisites

MEM23004A

Apply technical mathematics

MEM23109A

Apply engineering mechanics principles

It is also recommended to have completed MEM30005A Forces, MEM23006A Fluids/Thermo, MEM30006A Stresses, so this is normally considered as a late stage Diploma subject (2nd year part time).
