Withdrawal Dates
Last Day to withdraw from this course:
  • Without financial penalty (full fee refund): Friday, 1 March 2019
  • Without academic penalty (including no fee refund): Friday, 10 May 2019


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

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 in a beam for a given load;
  •  Define and understand stresses and strains in beams, and how they arise from a given load;
  •  Calculate stress and strain distributions, transformations, and principal components within a beam;
  •  Explain and apply the integration method, the moment area theorem, and the superposition principle to calculating beam deflections.

Assessment Due Date Percentage 
Assignments 25%
final exam 50%
Computer Lab: Laterally-Loaded Piles 10%
Lab 1: Triaxial test (GL1) 10%
Lab 2: Liquefaction Test (GL:2) 5%

The test will cover Modules 1-3 (Stress and Strain, Pure Bending, and Beam Bending). The final exam will be comprehensive, but with a focus on Modules 4-7 (Flexural Deformation in Beams, Stress/Strain Transformation, Shear Stress in Beams, and Torsion). Please note that:

1. You cannot pass this course if you achieve a mark < 40% on both the test and the final exam.

2. Tutorials are designed around three key learning outcomes: (1) a summative assessment (weekly quiz) to gauge your knowledge/comfort with the material, (2) direct feedback on the weekly quiz problem to help review critical concepts, and (3) further guided practice on concepts and problem-solving skills through additional, non-assessed problem sets. You must attend your allocated tutorial stream or you will be given a fail grade for your quiz.

3. Quizzes are held at the beginning of 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 will be collected following the allotted time and marked on a pass/fail basis (no partial marks will be given). Quizzes cannot be made up if missed for any reason and no extra time will be given for late arrivals. Lecturers or tutors will go over quiz questions after the completion of the quiz to highlight key concepts and problem-solving steps. Solutions to quiz problems will be posted to LEARN at the end of each week.

4. Homework problems will be posted for each week or module in the course. These problems will not be collected or assessed, they are for your own practice and learning. Numerical answers will be made available, but no worked solutions will be posted. We strongly suggest that you take advantage of these homework problems to support your learning.

5. Lab Reports are due by 5.00 pm, three weeks after the laboratory class. They should be prepared according to the guidance given in the Department of Civil and Natural Resources Engineering Communications Portfolio Guide.

The report must be 8-10 pages long (including one for a title page and one for an executive summary). Other components are Introduction, Method, Results and Analysis, Discussion, Conclusions and References. Include sufficient information to make the report as comprehensive as possible. Additional calculations and data can be included in an appendix. No late submissions of lab reports will be accepted, regardless of the circumstances.

Additional Course Outline Information


You have to self-select your lab group through the My timetable system. However, this selection needs to be completed by 5.00 pm on Wednesday 27 March 2019. 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.

Lab group selections made after 5.00 pm on Wednesday 27 March 2019 will not appear on the published list, and affected students will be turned away from the lab. If for any reason you are experiencing difficulty choosing your preferred group please see the course coordinator early to help resolve this before Wednesday 27 March 2019

Where to submit and collect work

Lab Reports should be dropped into the homework boxes on Level 2 (Civil/Mechanical Engineering Building) next to room E15. Lab Reports have title pages, not coversheets.
