One two-hour lecture and a three hour tutorial per week. Three laboratories will need to be attended through the semester.

The primary goal of the course is to provide students with the skills and knowledge required to analyse stress, strain and failure in machine parts and to use simple design procedure to ensure adequate strength of mechanical components. On completion of the course, students should:

• Be proficient with fundamental principles in stress analysis and basics of design for strength;
• Have been exposed to understanding of real life failures of various mechanical machinery components;
• Have developed an understanding of the appropriate selection of materials relating to design for strength against failures;
• Be gaining the physical intuition necessary to idealize a complicated practical problem and have developed appreciation of the importance of appropriate but simple assumptions used in basic stress analysis calculations;
• Have an understanding of the responsibility of engineers for safe design of engineering 最新糖心Vlog and unfortunate consequences of failures, and loss of human lives.

Further material will be available through MyUni under the “Course Material” section for this subject.

Assignments and in-class quizzes are provided as part of the learning experience. Students are expected to enhance their knowledge, problem solving skills and understanding of the subject matter through completing the assignments and quizzes, so they are regarded as formative rather than summative. The assignments and quizzes are marked, with the mark contributing to the final grade for the subject to ensure that students actually do the assignments and quizzes and take them seriously. It also helps to assess whether the required graduate attributes are being developed.

The laboratory class is intended to provide students with some practical experience in using experimental techniques and the Finite Element Method as well as experience in report writing and communicating their results.

The examination is a summative assessment and is intended to assess the student’s knowledge and understanding of the course material and how it fits into the global engineering context.

Every week there will be a tutorial given out at the beginning of the session to be completed during that session. It is very difficult to complete the tutorial within the allotted time if students have not prepared for the session. The best preparation is to attempt questions out of any of the suggested textbooks in the subject area prior to the tutorial. An hour’s preparation in this manner is recommended before each tutorial.

One assignment will be given at the beginning of the year, and it is expected to require approximately fifteen hours of work.

Assignments: One semester long assignment worth 15%. 

Quizzes: 10% total. Quizzes will be due at the end of some tutorials (announced during the tutorial).

Laboratories: 5% each (10% total). Laboratories are due two weeks after attendance.

Exam: 65% total

Attendance at laboratories is compulsory. If the total mark for laboratories is less than 30% for that section, the student will automatically fail the subject.

Assignments will be marked for clarity, proper referencing, interpretation and justification of results. Justification and explanation of thought process can be as important as the final numerical answer given.

Submissions are to be handed in to the submission box on level 2 of Engineering South Building with a signed cover page. Submissions not having a cover page will not be marked.

It is strongly recommended that an electronic submission is also submitted to the “Digital dropbox” within MyUni. This ensures that they are timestamped and that there is a backup copy submitted in case there are problems later with the paper copy.

• Electronic submission file MUST be named in the format of “s(student number) Asst 1”. If you submit a file with a different filename, it will not be marked.
• An easy way to compile the assignment is to scan handwritten calculations and diagrams, and then to insert them into the main document.
• Your submission needs to include all appendices, etc within the file. Separate files will not be marked.

Any late submission will be marked at -10% penalty per calendar day late.

Marked assignments and quizzes will be returned in the “submission return” pigeonholes in the second floor of Engineering South (beside the elevator).

Students are encouraged to contact the lecturer as soon as possible if there is a problem with handing in assignments/quizzes so as to request a different deadline.
