Introduction to solid and structural mechanics: analysis of statically determinate structures; stress and strain; behaviour of beams and columns; analysis of deformations; torsion.

This course introduces emerging civil engineers to solid and structural mechanics. The aim is to provide the fundamentals for the analysis of problems involving statically determinate structures. It develops understanding of stress/strain relations, behaviours of beams and columns under applied loads, torsion of prismatic members, transformations of stresses and strains and deflections of determinate beams.

Learning Outcomes

  • At the conclusion of this course you should be able to:

  • Calculate and plot internal forces: axial forces, shear forces, bending moments, and torques;
  • Define and compute stresses and strains in beams for different loadings;
  • Calculate stress and strain distributions, transformations, and principal components;
  • Apply the integration method and the moment area theorem to calculating beam deflections
  •       Qualitatively describe the deformation of solid bodies under various loadings

Assessment Due Date Percentage 
final exam 50%
Lab report 15%
Quizzes (11) 5%
Test 30%

The test covers Modules 1-3. The final exam is comprehensive, with a focus on Modules 4-7. Please note the following information about assessments.

• A mark < 40% on both the test and final exam will result in a failing course grade.
• Tutorials are designed around two key learning outcomes: (1) guided practice on concepts and problem-solving skills through non-assessed problem sets, and (2) a formative assessment (weekly quiz problems) to gauge your knowledge/comfort with the material. You must attend your allocated tutorial stream or you will be given a fail grade for your quiz. Exceptions may be granted on an ad hoc basis, but this must be confirmed by the course coordinator before the tutorial session.
• Quizzes are held at the end of the tutorial sessions each week, and will cover material up to that point in the course with a focus on the specific material in lectures for that week. Quizzes cannot be made up if missed for any reason and no extra time will be given for late arrivals. The final quiz grade will comprise the top 9/11 quiz marks to allow students to miss up to two quizzes without penalty.
• Homework problems are posted for each week on LEARN. These problems are not assessed, they are for your own practice and learning. Numerical answers will be made available, and worked solutions will be posted at the end of the weekly quiz period. We strongly suggest that you take advantage of these homework problems to support your learning and attempt them before the tutorial sessions.

Additional Course Outline Information


You must self-select your lab group through the My timetable system. This selection needs to be completed by 5.00 pm on Wednesday 30 March 2022. If you have not self-allocated by this time, you will be allocated into a lab by the course coordinator. A list will be compiled of the members in each group, uploaded to LEARN and used to take attendance at each lab session. If a student misses their allocated session, it is their own responsibility to find a suitable replacement session that can accommodate an extra student.

Where to submit and collect work

Lab assignments must be submitted to the applicable assignment drop box on LEARN by 5.00 pm, three weeks after the allocated laboratory section. Late submissions will incur a 20% penalty per day late. Further instructions for the lab assignment are available on LEARN and on the provided lab assignment sheet.
