Nominal Hours: 54  Diploma/Adv Dip: Elective (Group 3)  Competency Based
Assessment Plan A: (One Semester: 18 weeks)
Updated Feb 2015
DYNAMICS (18 weeks)
Quiz = Computer Based Testing: Typically consists of practice mode (iTester) and assessment mode (Moodle).
Exam = Written test submitted on paper, all working shown neatly.
* Suggested corequisite  esp for early tests such as 10201 FBD and 10202 Adding Forces.
** Official prerequisite rather amiss. All of the mathematics in this unit is covered in compulsory Maths MEM300012A.

ASSESSMENT
(*CAUTION: This subject contains two unofficial prerequisites: MEM30005A Forces and MEM30006A Stresses. MEM30005A must be done prior (prerequisite), but MEM30006A can be done concurrently (corequisite) 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 computerbased
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.
This unit applies basic scientific principles and techniques in mechanical and manufacturing engineering situations, covering three branches of mechanics  Dynamics, Fluids and Thermodynamics.
