Brief Handbook Description: This unit teaches the student how to recognise where and how their theoretical skills can be applied to the practical situations that they may encounter in this field of design. The unit utilises assumed theoretical knowledge and skills to elucidate the stresses and strains that exit in the different categories of machine parts. It sets out to make the students familiar with the simplifications that are applied to arrive at the analytic expressions commonly used to analyse the individual categories parts. These simplifications usually begin by assuming that only particular types of loads are carried by each category. The resulting analyses provide approximations to the actual stresses and it is possible to have different degrees of simplifications, requiring more or less work, giving better or worse approximations. Should a particular part be used to carry loads that were not allowed for in the traditional method then some more appropriate method must be found or developed. An important aspect is to make the student practiced in a range of modern concepts, techniques and tools, and to be made aware of their strengths and limitations.

Options may be provided in the choice of design assignments. Biomedical engineering and vehicle design problems may be provided as options to more general machine design problems.
Assumed Knowledge: AMME2301 AND AMME2500 AND ENGG1802 AND MECH3361.

Time Commitment:
# Activity Name Hours per Week Sessions per Week Weeks per Semester
1 Lecture 2.00 1 13
2 Tutorial 2.00 1 13
3 Independent Study 5.00 13
T&L Activities: Tutorial: Depending on the size of the class tutorials will be divided into 1 or 2 groups and each group allocated to 1 or 2 tutors.

Independent Study: The time that students will need to commit depends on the kind of results that they intend to achieve. For a pass, a students will need to spend an average 5-8 hours on independent study including assignment work. For higher grades, students will need to be prepared to spend significantly more than this.

Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.

Learning outcomes are the key abilities and knowledge that will be assessed in this unit. They are listed according to the course goal supported by each. See Assessment Tab for details how each outcome is assessed.

Discipline Specific Expertise (Level 5)
1. Ability to apply modern fatigue life predictions in general to component parts.
2. Ability to design a bolted joint to carry shear loads.
3. Ability to use a numerical solver to arrive at optimal design dimensions and material properties, provided the invention part of the design is completed and only the size and shape of the design has to be settled.
4. Ability to design and make a space frame to carry specified loads and meet dimensional and functional requirements, such that it may be compared with competing frames.
5. Ability to consider the properties strengths and weaknesses of hydrodynamic bearings to lead to proper selection and maintenance.
6. Ability to design or select a coupling that has the appropriate attributes with respect to power and misalignments.
7. Ability to calculate the parameters that define a matched pair of spur gears, leading to the selection of multiple gear pairs in gearboxes.
8. Ability to apply considerations of geometrical and practical constraints in the design of parts and assemblies.
Information Skills (Level 4)
9. Ability to consider the range and evolution of CAD systems to aid in the selection of systems for particular duties, for today and in the near future.
10. Ability to use a modern kinematic and dynamic package that is integral with our solid modeler CAD system to simulate articulated machinery and determine joint loads between the parts.

# Name Group Weight Due Week Outcomes
1 Assignment No 100.00 Multiple Weeks 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
Assessment Description: Assignment: There will be 4 assignments, all of which will be equally weighted. The assignments will be collected at the beginning of the tutorial session, when work on the next assignment will be due to start. A penalty will apply for failure to do so. Tutors will not discuss assignments that are due to be handed in.

The first assignment deals with the application of a modern CAD system, and its integrated Finite Element Analysis package, to the design of simple but diverse types of assemblies.

The second assignment examines the designs of a space 3D frame to meet a simplified but realistic application.

The third, is devoted to the design of the gears for a speed reducing gear box.

The last will probably deal with the design of a clutch or brake for a train, truck or car.

Each assignment will be accompanied with example workings and a guide as to the requirements to achieve a pass and better.
Assessment Feedback: When the assignments are marked and returned, the coordinator will discuss in a following lecture the range of solutions proffered, those that followed unadvisable paths, those that were rigorous in their analysis, as well as those that were inventive and shed novel light of possible solutions.
Grade Type Description
Standards Based Assessment Final grades in this unit are awarded at levels of HD for High Distinction, DI (previously D) for Distinction, CR for Credit, PS (previously P) for Pass and FA (previously F) for Fail as defined by University of Sydney Assessment Policy. Details of the Assessment Policy are available on the Policies website at . Standards for grades in individual assessment tasks and the summative method for obtaining a final mark in the unit will be set out in a marking guide supplied by the unit coordinator.
Special Conditions to Pass UoS Marking guides provided with each assignment include a generalised step by step procedure for the particular type of design. The marks for each assignment are so graded that a pass may be easily achieved by the correct application of the basic principles. For marks above a pass, the students are challenged to do their own research and be creative The world requires from engineers firstly safety and utility but it also rewards inventiveness.
Policies & Procedures: The faculty attempts to maintain consistency and quality in its T&L operations by adhering to Academic Board policy. These policies can be found on the Central Policy Online site.
