slope and deflection of simple beams; column buckling – Euler's equation, end conditions and effective length, combined axial and bending stresses for short columns; torsion of circular shafts, thin-walled closed sections and solid rectangular sections; transformation of plane stresses – Mohr's circle of plane stresses, principal stresses and planes; inelastic bending – stress resultants, yield moment and ultimate moment capacity of elastoplastic sections, elastic and plastic section modulus, plastic hinges; product of inertia, principal axes and principal moments of inertia; unsymmetric bending; combined stresses due to axial force, shear force, bending moments and twisting moment; shear centre.

Subject learning objectives (SLOs) Upon successful completion of this subject students should be able to: 1. Model and analyse the behaviour of structural and machine components subjected to various loading and support conditions based on principles of equilibrium and material constitutional relationships. 2. Understand and apply the concept of stress and strain to analyse and design structural members and machine parts under axial load, shear load, bending moment and torsion. 3. Solve practical problems through evaluating the relationship between stress and strain. 4. Analyse composite beams and shafts. 5. Determine the deflections and deformations of loaded flexural members. 6. Analyse a structural member and machine part when loaded beyond its elastic limit (inelastic and plastic cases). 7. Develop communication skills within an engineering context.

Course intended learning outcomes (CILOs) This subject also contributes specifically to the development of the following Course Intended Learning Outcomes (CILOs): Design Oriented: FEIT graduates apply problem solving, design and decision-making methodologies to develop components, systems and processes to meet specified requirements. (C.1) Technically Proficient: FEIT graduates apply abstraction, mathematics and discipline fundamentals, software, tools and techniques to evaluate, implement and operate systems. (D.1) Collaborative and Communicative: FEIT graduates work as an effective member or leader of diverse teams, communicating effectively and operating within cross-disciplinary and cross-cultural contexts in the workplace. (E.1)

Teaching and learning strategies Student learning in this subject is facilitated through two sessions each teaching week. These sessions consist of one x 2.5-hour lecture and one x 1-hour tutorial consisting mainly of discussions and problem solving. As a student in this subject you are expected to attend and participate in all lectures and tutorials. Students are expected to read the course materials, e.g. lecture notes and indicated contents in the nominated textbook, and attempt the in-class examples in the lecture notes and the associated online questions (if applicable) before the lecture. The lecturer will focus on problem solving activities in small groups and any problematic materials in the lectures. In the tutorial sessions, students are encouraged to form groups and discuss among themselves the solution of problem sets, thus training them to adapt to real-life situations where problem solving is often a group effort. Towards the end of the tutorial sessions, the tutor will display the solutions and discuss them. Students are expected to attempt the tutorial questions before their scheduled tutorial. UTSOnline will be used in this subject for announcements, lecture material as well as online assignments/quizzes. NOTE: As an indication, a typical 6cp subject would normally assume a total time commitment (including class time) of approximately 150 hours, for an average student aiming to pass the subject).

Additional information Mechanics of Solids is a fundamental stubject for students majoring in civil and mechanical engineering. For both civil and mechanical engineering students, this subject will act as gateway for continuing in Civil Engineering and Mechanical Engineering subjects. In particular, students who fail the subject repeatedly will not be permitted to re-enrol in the subject and hence such students will need to re-consider their future studies because the subject Mechanics of Solids acts as an initial pre-requisite subject for many of the subsequent subjects.

Assessment In this subject there are several types of assessment activities from week 1 onwards that require students to practise applying new knowledge and/or skills and receive feedback either from the lecturer, their tutor or peers. These assessments include six online quizzes and four online assignments which all contribute to the final mark of the subject. All assessments will be made available in UTSOnline. Please note that the all online assessment tasks are through Pearson with detailed activation methods available at UTSOnline. Students should make themselves ready to access the Pearson resources. If you have any issue with the log-in the system, please contact the subject coordinator.

Special consideration If you believe your performance in an assessment item or exam has been adversely affected by circumstances beyond your control, such as a serious illness, loss or bereavement, hardship, trauma, or exceptional employment demands, you may be eligible to apply for Special Consideration. Late penalty Work submitted late without an approved extension is subject to a late penalty of 10 per cent of the total available marks deducted per calendar day that the assessment is overdue (e.g. if an assignment is out of 40 marks, and is submitted (up to) 24 hours after the deadline without an extension, the student will have four marks deducted from their awarded mark). Work submitted after five calendar days is not accepted and a mark of zero is awarded. For some assessment tasks a late penalty may not be appropriate – these are clearly indicated in the subject outline. Such assessments receive a mark of zero if not completed by/on the specified date. Examples include: a. weekly online tests or laboratory work worth a small proportion of the subject mark, or b. online quizzes where answers are released to students on completion, or c. professional assessment tasks, where the intention is to create an authentic assessment that has an absolute submission date, or d. take-home papers that are assessed during a defined time period, or e. pass/fail assessment tasks. Querying results If you wish to query the result of an assessment task or the final result for a subject: Assessment task: query the result with the Subject Coordinator within 5 working days of the date of release of the result. Final subject result: submit an application for review within 5 working days of the official release of the final subject result.

Academic liaison officer Academic liaison officers (ALOs) are academic staff in each faculty who assist students experiencing difficulties in their studies due to: disability and/or an ongoing health condition; carer responsibilities (e.g. being a primary carer for small children or a family member with a disability); and pregnancy. ALOs are responsible for approving adjustments to assessment arrangements for students in these categories. Students who require adjustments due to disability and/or an ongoing health condition are requested to discuss their situation with an accessibility consultant at the Accessibility Service before speaking to the relevant ALO.
