# Dynamics 2

Course code MECH2350
Available in 2016
Units 10
Level 2000

## Description

This course extends on concepts introduced in first year mechanics (GENG1001) to provide a solid foundation on the dynamics of rigid bodies. An introduction to modelling the dynamics of discrete mechanical systems is also provided, with a focus on understanding the physical meaning of solutions in terms of mode shapes and natural frequencies of vibrating systems.

Topics include: kinematics and kinetics of planar rigid bodies, an introduction to 3D rigid body dynamics, modelling of dynamic mechanical systems, analytical solutions of linear models, and mode shapes and natural frequencies of multiple degree-of-freedom systems.
