Quiz = Computer Based Testing: Typically consists of practice mode
(iTester) and assessment mode (Moodle).
Exam = Written test submitted on paper, all working shown neatly.
*Where applicable.
Download Videos from the Server
There is a collection of videos that can be downloaded from the server (in the location shown below). There are a few extra videos here, but most of them are needed to cover this subject.
Note: This is several gigabytes altogether, so you will need a large USB memory stick or a portable drive.
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.
