Learning & Teaching Activities
Learning & Teaching ModesTeaching for this large class will consist primarily of lectures where the fundamental theory will be presented, followed by examples to illustrate how the theory can be applied to solve practical
engineering mechanics problems. Students will conduct 5 laboratory experiments (a 2.5 hour time frame in total) to see physical demonstrations of the type of material behaviour that is described in
the lectures. Students will develop their understanding of the course content through reading of the textbook, practice problem solving through the tutorial questions and attendance at lectures where problem solving strategies are presented and discussed.
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.There are 4-hours of lecture/tutorial timetabled for each of the 12 weeks in the semester. It is expected that students will spend another 4 to 6 hours per week outside of class studying the material and practising their problem solving with examples from the textbook.

Specific Course RequirementsAll experiments (tension, compression, torsion and column buckling) are video recorded and will be used in parallel with lecture slides. In particular, calculations based on experimental measurements will be used in class to illustrate the theoretical aspects of all above mentioned tests. Students are not required to attend practical classes, but expected to observe the experiments through these videos and answer questions related to the theory in each experiment.
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
Assessment SummaryAssessment Summary:
Final Examination 60%
Homework: There will be homework assignments set on each topic (about 10 in total) throughout the course. These will typically consist of 2 – 3 problems per assignment and will be submitted, marked and returned regularly throughout the semester. Marks on these assignments will make up 20% of the final subject mark. The assessment tasks associated with the Homework Exercises address course learning objectives 1, 2 and 3.
Quizzes: There will be two Quizzes (formative) during the semester, each worth 10% of your final mark. The Quizzes will be closed book, closed note and run under examination conditions. Quiz No. 1 will take place in Week 6 (Thursday) and cover the material listed above for Chapters 1 through 3 of the lecture topic. Quiz No. 2 will take place in week 10 (Friday) and cover the material listed above for Chapters 4, 6 and 7 of the lecture topic. If you miss a quiz through medical reasons, please come and see me. The assessment tasks associated with the Quizzes address course learning objectives 1 and 2.
Final Examination: The final examination (summative) will cover all the materials covered during the semester and contribute towards 60% of the final mark for the subject. The assessment tasks associated with the Final Exam address course learning objectives 1 and 2.
Assessment Related Requirements
You must obtain at least 30% in the final examination and 50% overall to pass the course.
Assessment DetailHomework Assignments – students will be given a set of problems (usually 2 to 3) covering the lecture material for each of the Chapters identified previously in Section 5.1. The homework should be done by students individually and will be marked with equal importance given to (a) presentation, (b) method and (c) the answer. Solution should start with a clear statement of the problem, a summary of the given information, what is to be solved for, and then a clear and easy-to-follow solution with diagrams where appropriate and highlighting any assumptions made along the way.
Quizzes – the in-class quizzes will be run under final examination conditions (that is, closed-book, closed-notes) and are intended to give both the instructor and students feedback on how well they are going in gaining an understanding of the fundamental theory and how to apply it to solve basic strength of materials problems.
Final Examination – this is intended to provide an independent test of how well students have learned the fundamental theory and their ability to apply it to solve strength of materials problems.
SubmissionHomework Assignments must be submitted to the course submission box in front of the School of Civil, Environmental and Mining Engineering Office (Eng. North N136) before the start of the nominated due
date. Late submissions will be penalised at the rate of 10% per day until the assignments are returned within a week. No credit will be given for assignments handed up after they have been marked and returned to the class.
In-class Quizzes will be marked and returned to students as soon as possible after the fact; normally about 1 to 2 weeks afterwards. Students who miss a quiz without providing a medical certificate will
receive zero (0) for the quiz.
Grades for your performance in this course will be awarded in accordance with the following scheme:

Final results for this course will be made available through Access Adelaide.
The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
