Show me unit information for year

Unit Snapshot

  • Enrolment information

    This unit applies the engineering principles and design techniques from ENG20001 - Mechanics of Materials AND MECH2002 - Introduction to Mechanical Design and Manufacturing, including force analysis in beams, shells and irregular structures, reaction forces and moments, and generating shear force and bending moment diagrams. Students will use apply their knowledge of manufacturing techniques and use computer aided design (CAD) software (SolidWorks) to design machine components and prepare engineering drawings.

Unit description

Provides students with the fundamental theory of mechanical design and how to apply this in designing and analysing a wide range of machine components. Students will gain an understanding of the basic and advanced elements used in machine design. These include the characteristics of gears, bearings, shafts, keys, fasteners, weldments, springs, brakes and clutches, and flexible elements. It also provides analytical and case-based knowledge to make machines as integrated systems of machine elements.

Learning outcomes

Unit Learning Outcomes express learning achievement in terms of what a student should know, understand and be able to do on completion of a unit. These outcomes are aligned with the graduate attributes. The unit learning outcomes and graduate attributes are also the basis of evaluating prior learning.

On completion of this unit, students should be able to:

design typical machine components and joints against possible modes of failure, including yield, fracture and fatigue

apply formal procedures of engineering design and the methods for choosing between competing alternatives, and develop skills in recording design calculations and reasoning in a workbook

demonstrate an understanding of safety issues, risk management and legal responsibility in engineering design

conduct and document design work as a team using CAD software package.
