Aims & Objectives:

During the unit, we aim:

• To derive, as with other engineering units, satisfaction and enjoyment from the exploration and special understanding of the physical world that is available only to engineers.
• To develop the ability to analyse and solve problems involving particles and rigid bodies in plane motion.
  
  

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

• Understand the basic machine dynamic principles of simple machine elements.
• Be prepared to study higher-level machine dynamics (Machine Dynamics 2).

Teaching Methods:

Assessment:

Generic Skills Outcomes:

• 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
