### Assessment summary

• Assignments: There will be 3 major assignments throughout the semester. Most assignment questions are real-life examples designed to increase the accessibility of the principles in mechanics of solids and raise the appeal of the subject. The assignment guidelines and questions can be viewed/downloaded from the course website in the Assignments section.
• Quizzes: The course will one open-book quizze during the lecture time. You will be asked to implement your knowledge to solve a solid mechanics problem. The aims are to assess your analytical and calculation skills, and provide you with early stage feedback about your individual progress in this course.
• Laboratory: There will be laboratory classes that will be prerecorded in Week 9 and uploaded to Canvas. Participation in the lab class and lab report contribute to your total course mark. For details, please go to the Laboratory section on the course website.
• Final Exam: The final exam will take place in the formal examination period at the end of the semester. It will be a closed-book exam. The structure of the exam will be discussed in detail in Week 12.

### Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

When you don’t meet the learning outcomes of the unit to a satisfactory standard.

### Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

• Deduction of 5% of the maximum mark for each calendar day after the due date.
• After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

5%/day penalties for the later submission.

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

## Learning support

### Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

### Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

### Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

### Attendance and class requirements

The whole of UOS will be delivered online.

The lecturing will be pre-recorded and uploaded to Canvas. The lecturer will also answer the questions and review the main points during the normal lecturing time.

All students are required to attend the on-live tutorial classes and some sessions will be recorded and uploaded to Canvas.

The lab will be recorded and uploaded to Canvas and then student need to watch the recording and finish the lab report.

### Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

All readings for this unit can be accessed through the Library eReserve, available on Canvas.

## Learning outcomes

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

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

• LO1. work and communicate with others in the tutorial sessions
• LO2. understand the fundamental principles of elementary solid mechanics and basic methods for stress and deformation analysis of a simple solid structure or element
• LO3. analyse problems in terms of strength and deformation in relation to the design, manufacturing and maintenance of simple solid structures
• LO4. demonstrate an understanding of the applicability of simple stress analysis methods
• LO5. demonstrate an understanding of when and why to do deformation analysis
• LO6. model structures composed of bars and beams
• LO7. apply boundary conditions for simple structural problems
• LO8. demonstrate an understanding of how and why to use energy methods for structural analysis
• LO9. perform fundamental buckling analysis

The graduate qualities are the qualities and skills that all University of Sydney graduates must demonstrate on successful completion of an award course. As a future Sydney graduate, the set of qualities have been designed to equip you for the contemporary world.

 GQ1 Depth of disciplinary expertise Deep disciplinary expertise is the ability to integrate and rigorously apply knowledge, understanding and skills of a recognised discipline defined by scholarly activity, as well as familiarity with evolving practice of the discipline. GQ2 Critical thinking and problem solving Critical thinking and problem solving are the questioning of ideas, evidence and assumptions in order to propose and evaluate hypotheses or alternative arguments before formulating a conclusion or a solution to an identified problem.
