You must either have successfully completed the following subject(s) before starting this subject, or currently be enrolled in the following subject(s) in a prior study period; or enrol in the following subject(s) to study prior to this subject:
Please note that your enrolment in this subject is conditional on successful completion of these prerequisite subject(s). If you study the prerequisite subject(s) in the study period immediately prior to studying this subject, your result for the prerequisite subject(s) will not be finalised prior to the close of enrolment. In this situation, should you not complete your prerequisite subject(s) successfully you should not continue with your enrolment in this subject. If you are currently enrolled in the prerequisite subject(s) and believe you may not complete these all successfully, it is your responsibility to reschedule your study of this subject to give you time to re-attempt the prerequisite subject(s)

The subject aims to engender enthusiasm for design and to provide the basis of sound design methodology, together with fundamental material selection and component design. Design methodology includes decision making, proper recording of design calculations and decisions in design reports, accountability and legal aspects of design calculations. Factors of safety are emphasised with balanced design of simple components.
Considerations of static failure design for bending and torsions, stress analysis, along with linear actuators and springs, eccentrically loaded bolted and welded connections, cyclic loads, stress raisers and design of shafts to AS1403. Other design methods include fracture mechanics, fatigue, design of spur gears for bending, strength and surface durability and disc brake and multi-plate clutches.
