Learning Outcomes

By the end of this course, students will be able to:
  1. Apply theories of work, power and efficiency to mathematically model mechanical systems for analysis and design. (Capability 3.1)
  2. Understand some common mechanical power system elements including motors, shafts, keys, couplings, bearings, gear, belt and chain drives, and be able to complete calculation and selection tasks for selected elements in a design context while applying safety and service factors (Capability 3.1 and 5.1)
  3. Create and interpret sets of mechanical engineering drawings using CAD, with consideration to tolerances, limits and fits. (Capability 6.1)
  4. Identify and critically evaluate ethical dilemmas in an engineering design project (Capability 8.1)
  5. Complete design projects using systematic concept design methods in the framework of a stage-based design process giving consideration to cost, applying basic project management skills and tools, and communicating the design in written and graphical forms. (Capability 3.1, 5.1, 6.1 and 7.1)
  6. Find external information in manufacturers' catalogs and online, and apply it to specific design-related tasks at hand (Capability 8.2)

Workload Expectations

This course is a standard 15 point course and students are expected to spend 10 hours per week involved in each 15 point course that they are enrolled in.

For this course, each week you can expect 3 hours of lectures, 2 hours of tutorials, and in some weeks, 2 hours of labs.

You should also spend 5 hours of individual and teamwork per week. This will involve studying course content, working on coursework assignments and projects, and preparing for the examination.

Delivery Mode

Campus Experience

Up to 3 x 1-hr lectures each week. Some lecture slots will not be used, and it is expected that the time will be spent working on design projects.

2 x 1-hr design office tutorials each week

4 x 2-hr laboratory sessions during the semester.

Attendance is required at some scheduled activities to complete and receive credit for course components.

Lectures will be available as recordings. Other learning activities including tutorials and labs will not be available as recordings or in online format.

The activities for the course are scheduled as a standard weekly timetable.

Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

Health & Safety

Lab inductions must be completed to participate in and gain marks for the labs.  Students are expected to adhere to the guidelines outlined in the Health and Safety section of the Engineering Undergraduate Handbook.

Student Feedback

At the end of every semester students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback and respond with summaries and actions.

Your feedback helps teachers to improve the course and its delivery for future students.

Class Representatives in each class can take feedback to the department and faculty staff-student consultative committees.

We intend to further clarify the connection of lecture content to the knowledge required for the projects, and provide enhanced guidance for the gear reducer design project.

Students are encouraged to provide any feedback to the teaching staff during the semester, as well as in the final SET survey.

Academic Integrity

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed for potential plagiarism or other forms of academic misconduct, using computerised detection mechanisms.

Class Representatives

Class representatives are students tasked with representing student issues to departments, faculties, and the wider university. If you have a complaint about this course, please contact your class rep who will know how to raise it in the right channels. See your departmental noticeboard for contact details for your class reps.

Inclusive Learning

All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.

Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website http://disability.auckland.ac.nz

Special Circumstances

If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.

If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page https://www.auckland.ac.nz/en/students/academic-information/exams-and-final-results/during-exams/aegrotat-and-compassionate-consideration.html.

This should be done as soon as possible and no later than seven days after the affected test or exam date.

Learning Continuity

In the event of an unexpected disruption, we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and course assessment continues to meet the principles of the University’s assessment policy. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator/director, and if disruption occurs you should refer to the university website for information about how to proceed.

Student Charter and Responsibilities

The Student Charter assumes and acknowledges that students are active participants in the learning process and that they have responsibilities to the institution and the international community of scholars. The University expects that students will act at all times in a way that demonstrates respect for the rights of other students and staff so that the learning environment is both safe and productive.
