  • First semester 2017 (Day)


  • First semester 2017 (Day)


This unit introduces second year mechanical engineering students to the concepts of time, space, coordinate systems, particles, rigid bodies, forces, work, energy and Newton's Laws of Motion. Students will be taught the fundamentals of kinematics and kinetics of rigid bodies and systems of particles and to carry out dynamic analysis to balance systems with rotating and reciprocating masses. Students will also be introduced to 3-dimensional dynamics of rigid bodies. The fundamentals of mechanical vibration, analysis and synthesis of planar mechanisms and experimental modelling will complete the unit.


At the successful completion of this unit you will be able to:

  1. Solve engineering problems involving: displacement, velocity and acceleration, simple vibrating systems of masses, springs and dampers, and analysis of simple engineering mechanisms.
  2. Analyse forces, power and energy losses involved in practical engineering applications.
  3. Describe engineering solutions in a realistic and logical format using the appropriate units, dimensions and accuracy.
  4. Address the fundamentals of kinematics and kinetics of particles and rigid bodies.
  5. Quantify dynamically balanced systems with rotating and reciprocating masses.


Problem solving tests: 10% + Mid semester test: 10% + Laboratory/build and test project: 10% + Examination (3 hours): 70%

Students are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.

Workload requirements

3 hours lectures, 3 hours problem solving/laboratory classes and 6 hours of private study per week
