Sample subject outline - Semester 1 2013

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

Rationale

As an engineer, you will need to analyse and design engineering components and systems such as buildings, bridges, roads, airports, power stations, etc. To do this you must have an understanding of the basic principles of applied mechanics, and of the interaction of the components in a system. This is the next unit after Engineering Statics and Materials (ENB110), that provides the basic knowledge and skills required for the above purposes. The principles established in ENB110 are also essential for further studies throughout the remainder of your degree studies.

Aims

The aim of this unit is to build on your existing knowledge of basic statics by introducing principles, applications and problem solving of flexible body mechanics and strength of materials.

Objectives

On completion of this unit, you will be able to:
1.create and represent simple conceptual models of elastic 2-dimensional flexible bodies sustaining a set of forces in static equilibrium;
2.apply elasticity relationships to determinate and indeterminate structures, to determine the stresses, strains and potential failure within those structures;
3.apply engineering design principles to construct, test and analyse a simple structure;
4.manage and document individual development of the practical project.

Content

Mechanics of Materials particularly in relation to timber.

• Normal and shear stresses in uniaxial members;


• Centroids and Second moment of Area;


• Shear Flow;


• Sectional properties and deflections of beams.


• Bending moment and shear in indeterminate beams and determinate frames;


• Transformation of stresses in 2D and Mohr's circle


• Torsion in circular members;


• Compatibility;


• Combined loading of structural members; and


• Buckling in slender columns.

Approaches to Teaching and Learning

Teaching Mode:
Hours per week: 4
Lectures: 3 hrs per week (including 1 hour of consultation on the project as required. )
Tutorials: 1 hr per week

A peer mentored drop-in centre will also be available at specific times where you can interact individually or in a small group with senior students or tutors to improve your understanding of recent lecture material.

The weekly 3-hour session will guide you through the unit and describe and illustrate the key concepts using real examples, practical demonstrations and visual aids. Ongoing reference to, and directions about, your project will be interwoven throughout lectures with the final hour open for individual as well as class consultation with lecturer.

Tutorial classes are primarily for working on problems and solutions collaboratively Tutors are either lecturers or postgraduate students. Problem solving knowledge and skills are developed and assessed via online exercises (with different variables to prevent rote copy) with due dates to keep you on track and multiple opportunities to receive feedback and resubmit work.

In a small group your group will design, analyse, build and test a model structure. This will develop active learning-through-experience and reflective peer review on integrating theory with practice and real materials.

Assessment

Assessment for this unit consists of problem solving tasks with formative and summative feedback throughout the semester; a design, build and test project and a final exam.Formative feedback
You will receive oral feedback on your progress in this unit during tutorials and discussions throughout the semester. Additional formative feedback will be available in drop-in centre and the project consultation time. The problem solving tasks given in week 2 will provide ongoing feedback for practice until the final submission in week 9.

Summative feedback
Assessment 1: Problem solving tasks
Mode of feedback: Electronic submission and feedback from commencement of the assignment until final submission as per the assignment brief. Ongoing opportunities for feedback until end of semester.

Assessment 2: Project
Mode of feedback: class feedback and guidance in lectures and the consultation time with supplementary support in the drop-in sessions.

Assessment 3: 2 hour Exam
Due date: Exam period

Assessment name: Examination (written)
Description: You will solve problems related to key concepts in engineering mechanics of materials covered over the semester.

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.

Additional Cost Statement:
You will be engaged in a project. You will be required to purchase the materials for constructing your project at your expense, and provide the facilities and tools required to construct your project. You will also need to provide the correct stationery, printing, binding and submission envelope for the report.

Risk assessment statement

You will undertake lectures and tutorials in the traditional classrooms and lecture theatres. As such, there are no extraordinary workplace health and safety issues associated with these components of the unit.

No testing of material components or construction of the project will be allowed in QUT labs or premises. All project work, other than group discussions, theoretical research and final testing of the completed project, must be undertaken off site.

You will be required to test your project 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 be denied access to laboratories if you do not have a safety induction card.

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