The unit 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.

At the completion of this unit students will be able to:

  1. apply an appropriate design methodology and discuss the legal implications of the design process
  2. select appropriate materials to satisfy design requirements
  3. explain material behaviour and simply failure mechanisms and design for these situations
  4. design mechanical components for strength and deflection with regard to safety standards
  5. correctly select standard components from manufacturer's catalogues.

Mandatory conditional prerequisites

You must either have successfully completed the following unit(s) before starting this unit, or currently be enrolled in the following unit(s) in a prior study period; or enrol in the following unit(s) to study prior to this unit:

Please note that your enrolment in this unit is conditional on successful completion of these prerequisite unit(s). If you study the prerequisite unit(s) in the study period immediately prior to studying this unit, your result for the prerequisite unit(s) will not be finalised prior to the close of enrolment. In this situation, should you not complete your prerequisite unit(s) successfully you should not continue with your enrolment in this unit. If you are currently enrolled in the prerequisite unit(s) and believe you may not complete these all successfully, it is your responsibility to reschedule your study of this unit to give you time to re-attempt the prerequisite unit(s).
