Aims & Objectives:

During the course, we aim to:

• Develop an understanding of structural and material behaviour
• Develop skills in analysis of statically determinate and indeterminate structures
• Understand basic design formulae against structural and material failure

At the completion of this unit, students should be able to:

• Develop an understanding of structural and material behaviour
• Analyse statically determinate and indeterminate structures
• Apply the failure theories in design simple structures and machine components

Teaching Methods:

Lectures (36 hrs), Laboratory work (6hrs), Tutorials (18 hrs)

Assessment:

Final examination (60-80%), Laboratory reports (10-20%), Mid-Semester test (10-20%)

Generic Skills Outcomes:

• Ability to apply knowledge of basic science and engineering fundamentals
• Ability to communicate effectively, not only with engineers but also with the community at large
• Ability to undertake problem identification, formulation and solution
• Ability to function effectively as an individual and in a multi-disciplinary and multi-cultural teams, with the capacity to be a leader or manager as well as an effective team member
• Understanding of professional and ethical responsibilities and commitment to them
• Expectation of the need to undertake lifelong learning, and capacity to do so
