Description

This unit provides a thorough coverage of the principles of motion and dynamics of particles and rigid bodies, and applications of these to mechanical systems.The basic concepts of vibration analysis are also introduced.

Prerequisite Rule

Students must pass 2 units from ENS1101, MAT1236

Learning Outcomes

On completion of this unit students should be able to:

  1. Accurately describe kinematics of particles and system of particles.
  2. Analyse problems related to planetary motion and vibrations of machines and engineering structures and apply this when undertaking related design work.
  3. Apply knowledge of kinematics, kinetics, inertia and gyroscopic motion to the design of simple mechanical and structural systems.
  4. Solve a wide variety of engineering dynamics problems in free space mechanics and general planar motion.

Unit Content

  1. Gravitational force, gravity, motion of planets and satellites.
  2. Kinematics of particles: rectilinear and plane curvilinear motion, motion in various coordinate systems, space curvilinear motion, relative motion, constrained motions of connected particles.
  3. Kinetics of particles: Newtons second law of motion, inertial system, work and energy, impulse-momentum principle, central-force motion.
  4. Kinetics of system of particles: work-energy relation, impulse-momentum, conservation principle, steady and variable mass flow problems.
  5. Plane kinematics of rigid bodies: rigid body motion, rotation about a fixed axis, relative motion, instantaneous centre.
  6. Plane kinetics of rigid bodies: force, mass and acceleration; plane-motion equations, general plane motion, work-energy relation, acceleration from work-energy, virtual work, interconnected rigid bodies.
  7. Three-dimensional dynamics of rigid bodies: rotation about a fixed point, fixed-axis rotation, parallel-plane motion, momentum and energy equations of motion, gyroscopic motion.
  8. Vibrations: simple harmonic motions, free vibration, forced vibration, resonance, damping, vibrations caused by earthquakes.

Additional Learning Experience Information

Lectures, tutorials and laboratory sessions.

Disability Standards for Education (Commonwealth 2005)

For the purposes of considering a request for Reasonable Adjustments under the Disability Standards for Education (Commonwealth 2005), inherent requirements for this subject are articulated in the Unit Description, Learning Outcomes and Assessment Requirements of this entry. The University is dedicated to provide support to those with special requirements. Further details on the support for students with disabilities or medical conditions can be found at the Access and Inclusion website.

Academic Misconduct

Edith Cowan University has firm rules governing academic misconduct and there are substantial penalties that can be applied to students who are found in breach of these rules. Academic misconduct includes, but is not limited to:

  • plagiarism;
  • unauthorised collaboration;
  • cheating in examinations;
  • theft of other students' work;

Additionally, any material submitted for assessment purposes must be work that has not been submitted previously, by any person, for any other unit at ECU or elsewhere.

The ECU rules and policies governing all academic activities, including misconduct, can be accessed through the ECU website.
