|Brief Handbook Description:||The primary objective of this unit is to understand internal actions (forces and moments) in structures (deformable objects) under loads in three key areas: how structures resist external loads by internal actions; the distribution of internal actions within structures; and the deformations, stresses and strains associated with the internal actions. At the end of this unit, students should be able to understand the basic methods of load transfer in structures - tension, compression, bending, shear and torsion (internal actions); apply the equations of equilibrium to determine the distribution of internal actions in a simple structure by drawing BMDs, SFDs, AFDs, and TMDs; understand the significance and methods of calculation of the geometric properties of structural sections (I, Z, S, J etc); understand the effect of internal forces and deformations of bodies through the concept and calculation of strains and stresses; appreciate the behaviour of structures by analysing structures without numerical calculations; display a knowledge of basic material properties, combined stresses and failure criteria; and demonstrate their hands-on experience of the behaviour of structural members via experiments and the ability to prepare written reports on those experiments. Emphasis in the assessment scheme will be placed on understanding structural behaviour and solving problems, rather than remembering formulae or performing complex calculations. The course seeks to utilise and improve the generic skills of students, in areas such as problem solving, neat and logical setting out of solutions, report writing, and team work. The syllabus comprises introduction; equilibrium; internal actions: BMDs, SFDs, AFDs, and TMDs; elasticity, stress and strain, and basic material properties; axial forces: tension and compression; elastic bending of beams; shear force and shear stresses in beams; torsion; deflection of beams; pipes and pressure vessels; trusses; material properties, combined stresses and yield criteria; advanced bending; introduction to buckling and instability.|
|Assumed Knowledge:||From ENGG1802 Engineering Mechanics, students should be competent in the following areas. 1. The concept of force and momentum equilibrium in two and three dimensions. 2. Drawing free body diagrams. 3. Establishing and solving the equations of equilibrium from the FBD. 4. Setting out solutions logically, clearly and neatly. Students should be competent incertain mathematical skills. 1. Solving algebraic equations. 2. Differentiation and integration (including double integrals). 3. Drawing graphs of polynomials (especially) and other mathematical function. 4. Trigonometry.|

|T&L Activities:||Tutorial: A 2 hour tutorial session is timetabled weekly. A variety of activities will take place during the tutorial sessions, such as discussion of problems, formative assessment tasks, and a laboratory session. The majority of the time in tutorials will be allocated for students to work on the problem questions. Students should attend their allocated tutorial group and room. On some occasions there may be a joint “briefing” for all students in a common location . There will be a compulsory laboratory session during the tutorial in March. Assessable quizzes have been scheduled during some tutorial sessions. Regular attendance and participation in tutorials, and attempting problems before the allocated session, are considered important for successful understanding and performance in this unit of study
Laboratory: Students are required to attend two laboratory sessions during the semester. This gives students the opportunity to experience some structural behaviour at close hand. The results of the experiments will be compared with the theory developed in lectures and tutorials. One session will be a small introduction to material properties (held during a tutorial session) and the second is designed to be “self-serve” and performed without supervision. There will be a compulsory laboratory session during the tutorial in March. The 2nd laboratory session is to be performed at a time of the students’ convenience and should take no more than 2 hours to perform. Written reports will be required on both sessions as part of assessment.
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.
|Attribute Development Method||Attribute Developed|
|Basic equation solving and equilibrium calculation skills.||Maths/Science Methods and Tools (Level 2)|
|Information literacy is an important part of this unit of study as students will receive data in a variety of forms: printed, WWW, email, experimental, and will use a variety of tools and resources to solve problems.||Information Seeking (Level 2)|
|Communication skills are developed by having a series of assignments that work towards an important final report, and by using student peer review, concentrating on how well the student has communicated the solution process, as an integral part of the assessment process.||Communication (Level 2)|
|Ethical, social and professional understanding is considered by including relevant, topical and modern examples in the syllabus, while also covering some important historical developments.||Professional Conduct (Level 1)|
For explanation of attributes and levels see Engineering & IT Graduate Outcomes Table.
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.Maths/Science Methods and Tools (Level 2)
Assignment: There will be some “formative assessment” task undertaken during some tutorial sessions. These tasks are not worth marks, but are primarily designed to give both the students and lecturer feedback on level of performance.
Assignment: Students are expected to submit some problems at regular intervals in the form of assignments. The problems will not be marked in detail – they will be checked for the correct procedure and adequate presentation/setting out. A solution will be available, and it is each student’s responsibility to check his/her submission with the solution. The lecturer will attempt to return the submissions within a week to ensure timely feedback to the students. There will be two assignments during the semester. More details on the assignments will be provided on a separate information sheet.
Quiz: There will be 5 short (approximately 1 hour or less) quizzes held during the semester. The main aim of the quizzes is to examine the students’ understanding of the main concepts in the unit of study covered to that date, without excessive calculations. The quizzes will provide feedback to the students on their individual performance, and help the lecturer identify students at risk.
Lab Report: Written reports will be required on both laboratory sessions.
Final Exam: There is a 2 hour examination at the end of the semester. The questions will be of a similar format to the type 1 (basic), type 2 (intermediate), and type 3 (advanced) questions given in the problem sets. The exam questions will require both calculations and explanation-type answers, to test understanding of the subject. The final examination is partial open book. Students are permitted to bring in annotated versions of the lecture notes book and a programmable calculator. No additional written material is permitted in the examination room. More details on the format of the examination will be given in lectures, and the nature of the examination described above is subject to change.
