Requisites

Pre-requisite: CIV1501 or Students must be enrolled in the following Program: GCEN

Overview

A knowledge of the basic laws of dynamics, vibration and mechanisms are fundamental for the solution of many engineering problems. This course develops, at an appropriate level, theoretical and practical methods used in the design of machine elements.

Course learning outcomes

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

  1. analyse the kinematics of planar motion of a particle and rigid body;
  2. use the free body diagram method to solve simple problems involving the forces particles and rigid bodies and their resulting planar motion;
  3. calculate the velocity and acceleration of any point within a simple 2D mechanism;
  4. apply the principles of work-energy and impulse-momentum to the analysis of simple bodies in 2D motion;
  5. calculate the dynamic forces resulting from rotating out-of-balance masses and determine the corrective masses to balance that system;
  6. determine the dynamic behaviour of a range of common engineering devices;
  7. analyse the vibrational response of simple single-degree-of-freedom systems to determine damped and undamped frequencies, amplitude and the forces transmitted to the system's support.
