Requisites
Pre-requisite: (MEC2401 and (MAT2500 or ENM2600)) or Students must be enrolled in one of the following Programs: MENS or MEPR or GCNS or GDNS or GEPR
Overview
A feature of dynamics is that objects including particles and rigid bodies move. Parts are subject to forces, causing them to accelerate. They impact on each other, the resulting impulses causing changes in momentum. Parts spin and must be balanced while gyroscopic forces operate. Rigid bodies in space are subject to gravitational fields and propulsive thrusts. Fluctuating forces cause vibrations that can have many modes that must be damped out.
The student of the course of Advanced Dynamics must develop the ability to analyse and synthetise all of these.
Such ability comes with a cost. Motions, forces, momentum and energy are all subject to mathematical equations, many of them of an advanced nature. In mastering the fundamentals, the student will come to grips with differential equations, vectors, operators, matrices and tensors. These skills are built up as understandable solutions to practical engineering problems, illustrated where possible by real-time simulations.

Student workload expectations
To do well in this subject, students are expected to commit approximately 10 hours per week including class contact hours, independent study, and all assessment tasks. If you are undertaking additional activities, which may include placements and residential schools, the weekly workload hours may vary.
