Sample subject outline - Semester 1 2013

Note: Subject outlines often change before the semester begins. Below is a sample outline.

Rationale

As a mechanical engineer, you must have the expertise to analyse components and systems of components to produce efficient designs. In order to do this, you must understand the interaction of components in both mechanisms and structures; how structures carry loads and react to forces (stresses) they exert on each other. Stress analysis is an essential part of the design process that ensures the structural integrity of various structures, electromechanical devices and mechanisms. It is also an indispensable tool for optimizing structural design and meeting multidisciplinary performance requirements. Effective and efficient stress analysis results in lightweight, reliable and robust structures. This unit is located in second year and builds on your first year work in materials and statics in ENB110.

Aims

The aim of this unit is to build on existing knowledge of basic statics by introducing mechanics of materials, in preparation for later study of more complex structures and stress analysis.

Objectives

At the end of this unit, you should be able to:

• Apply the fundamental principles of mechanics of materials to formulate and calculate stresses in practical engineering components and systems.


• Analyse mechanical components, structures and systems for stress calculations using practical approaches.

Content

1. Stress and strain in simple members.
2. Deflections of bending beams and sectional properties
3. Transformation of stress and strain in 2D, Mohr circle
4. Torsion
5. Strain Energy
6. Thin walled structures
7. Combined loading of structures and machine members
8. Yield criteria for safe elastic loading
9. Buckling

Approaches to Teaching and Learning

No. of hours per week: 4 hours
Lectures: 2 hours
Tutorials: 1 hour
Labs: 1 hours (experimental labs)
The teaching in this unit is based around a series of lectures, tutorials and laboratory sessions which allow you to develop an understanding of the theoretical concepts (lectures) and then apply these concepts to model, test and verify solutions to engineering problems in practical sessions and tutorials. Many of the theoretical concepts will be explained using the development and solution of real engineering problems. As well as labs, you will complete a weekly online quiz to reinforce conceptual knowledge. Reference will also be made to relevant sections of the text.

Assessment

Assessment will be in the form of on-line quizzes, problem solving practical tasks and a written final examination.You will receive formative feedback on your progress throughout the semester in tutorials. Written and verbal feedback will be provided for problem solving tasks including laboratory work; assessment results and completed (marked) CRA sheets will be available for examinations.

Academic Honesty

QUT is committed to maintaining high academic standards to protect the value of its qualifications. To assist you in assuring the academic integrity of your assessment you are encouraged to make use of the support materials and services available to help you consider and check your assessment items. Important information about the university's approach to academic integrity of assessment is on your unit Blackboard site.

A breach of academic integrity is regarded as Student Misconduct and can lead to the imposition of penalties.

Resource materials

Resource material in the form of lecture notes and PowerPoint presentations are provided on the QUT Blackboard web site. This material is designed to supplement rather replace the material presented during the lecture and tutorials.

Risk assessment statement

You will be informed of any requirements pertaining to a safe workplace. In lectures, tutorials and such, the information will include location of fire exits and meeting points in case of fire. If you do not follow legitimate instructions or endanger the safety of others or do not act in accordance with the requirements of the Workplace Health and Safety Act, you will be required to leave the session.

You will be required to undertake practical sessions in the laboratory under the supervision of the lecturer and technical staff of the School. In any laboratory practicals you will be advised of requirements of safe and responsible behaviour and will be required to wear appropriate protective items (e.g. closed shoes or steel capped shoes).

You will undergo a health and safety induction before the commencement of the practical sessions and will be issued with a safety induction card. If you do not have a safety induction card you will be denied access to laboratories.

Disclaimer - Offer of some units is subject to viability, and information in these Unit Outlines is subject to change prior to commencement of semester.
