ISVR1034 Dynamics

Module Overview

This module comprises the dynamics components of the Mechanics, Structures and Materials module (FEEG1002) and is specifically for students on the Acoustics with Music joint honours degree programme. The fundamental principles of dynamics covered here provide a foundation and prerequisite for the Mechanics, Machines and Vibration module (FEEG2002) in part 2.

Aims and Objectives

Module Aims

This module aims to review the principles of dynamics and apply them to the solution of simple dynamic systems.

Learning and Teaching

Teaching and learning methods

Teaching methods include lectures, group tutorials and laboratory sessions. The laboratory concerns the measurement of transfer functions of a loudspeaker and the dynamic effects of structural modification. Learning activities include self-study and the solution of example problems both in a supervised environment and in your own time.
