# MEC3453 - Dynamics II

## 6 points, SCA Band 2, 0.125 EFTSL

#### Offered

Clayton First semester 2007 (Day)

Malaysia First semester 2007 (Day)

#### Synopsis

Students develop skills in analysing the response of a vibratory system to an external stimuli. Techniques for developing the equation of motion, defining the forcing function and analysing the vibratory response. Fundamental calculus for analysing mechanical vibrations and the generalised kinematics and kinetics of particles and rigid bodies using vector algebra. A systematic method of establishing a dynamic model with the associated forces and motion, a set of coordinate axis and the choice of derivation method for the governing equations for the model and solution techniques follows. Skills presenting results develop along with understanding the relevance of dynamics in engineering.

#### Objectives

Use of kinematics and kinetics in engineering problem solving
