Description
The objectives of this subject are to enable students to: acquire a fundamental understanding of the behaviour of structural components commonly used in engineered structures and machines; develop skills to help them 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. Content includes: pure bending of beams – flexural stress and strain, calculation of beam loads; shear flow and shear stresses in beams – distribution of shear stresses in beam sections, forces and stresses in shear connectors; composite beams – composite short columns; 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.

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 2 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).
