MEC 2301 Design of Machine Elements

STAFFING:

REQUISITES:

OTHER-REQUISITES:

SYNOPSIS:

Design is one of the most important engineering functions for it is through design that new products and processes are born and that old ones are improved. Design requires a breadth of knowledge extending over many areas, and a sound analytical ability. It requires an ability to recognise the phenomena involved and to synthesise an integrated solution. Design requires sound engineering judgement as well as a good grasp of the underlying basic science and mathematics. This course aims to integrate the knowledge that the student has gained earlier in their course and to focus the student's analytical skills towards synthesis of solutions by working through the design of several simple, commonly used devices.

OBJECTIVES:

On completion of this course, students should be able to:

1. identify appropriate analytical models to describe and predict the behaviour of standard machine components;
2. reduce the behaviour of a complex machine into appropriate sub- systems/elements and then analyse the behaviour of their elements;
3. apply stress analysis theory, fatigue theory and appropriate criteria of failure to the design of simple machine elements;
4. analyse and evaluate forces and stresses within a spur gear system;
5. design simple power transmission systems;
6. select appropriate mechanical components from manufacturers' catalogues;
7. design springs, plain bearings and fluid seals;
8. specify the appropriate use of adhesives;
9. apply codes and standards to machine component design;
10. communicate the results of a design assignment by means of drawings and a design report;
11. make appropriate use of available computer aided design software.

IMPORTANT ASSESSMENT INFORMATION

1. Attendance requirements:
   It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration.
2. Requirements for students to complete each assessment item satisfactorily:
   To complete each of the assessment items satisfactorily, students must obtain at least 50% of the marks available (or at least a grade of C-) for each assessment item.
3. Penalties for late submission of required work:
   If students submit assignments after the due date without prior approval then a penalty of 10% of the total marks available for the assignment will apply for each working day late.
4. Requirements for student to be awarded a passing grade in the course:
   To be assured of receiving a passing grade a student must achieve at least 40% in each of the summative assessments and at least 50% of the available weighted marks for the summative assessment items.
5. Method used to combine assessment results to attain final grade:
   The final grades for students will be assigned on the basis of the weighted aggregate of the marks (or grades) obtained for each of the summative assessment items in the course.
6. Examination information:
   In an Open Examination, candidates may have access to any material during the examination except the following: electronic communication devices, bulky materials, devices requiring mains power and material likely to disturb other students.
7. Examination period when Deferred/Supplementary examinations will be held:
   Any Deferred or Supplementary examinations for this course will be held during the examination period at the end of the semester of the next offering of this course.
8. University Regulations:
   Students should read USQ Regulations 5.1 Definitions, 5.6. Assessment, and 5.10 Academic Misconduct for further information and to avoid actions which might contravene University Regulations. These regulations can be found at the URL http://www.usq.edu.au/corporateservices/calendar/part5.htm or in the current USQ Handbook.
