TEXTBOOKS / RESOURCES

Finite Element Analysis in Practice (Autodesk) (Also here) This resource is 12MB and 266 pages and covers much of the content for this unit. Based on Inventor Professional 2011 and Algor, so some things will look a bit different, but the concepts are very much the same.

ASSESSMENT

(CAUTION: This subject contains most of MEM30006A Stresses, so you should do both together) 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. 

When you have completed this unit of competency you will have developed the knowledge and skills to determine the resultant and equilibrant of systems of forces, in one plane, then determine nominal sizes for a simple horizontal beam subject to a combination of uniform and point loadings.
