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

Understand the analysis and synthesis of mechanisms and machines.
Ability to design mechanisms for real, unstructured engineering problems.

Teaching Methods:

Lectures (36 hrs); Tutorials (18 hrs); and Laboratory (6hrs)

Assessment:

Tests (15%), Laboratory Assignment (15%), Examinations (70%)

Generic Skills Outcomes:

In this unit, students are expected to enhance the Key Generic Skills below as recognised by Engineers Australia. The Unit Outline explains how these outcomes will be achieved.

Ability to apply knowledge of basic science and engineering fundamentals
Ability to communicate effectively, not only with engineers but also with the community at large
Ability to undertake problem identification, formulation and solution
Ability to function effectively as an individual and in a multi-disciplinary and multi-cultural teams, with the capacity to be a leader or manager as well as an effective team member
