Learning Outcomes
1. Analyse 2 DoF vibrating systems for modal frequencies and shapes and response to harmonic excitation
2. Determine the wave equation for 2nd & 4th order systems and apply boundary conditions to define mode shapes. Perform modal and forced-vibration analyses of simple continuous systems.
3. Develop modelling strategies for multiple DoF simulation
4. Formulate a State variable model of mechanical and other systems
5. Build dynamic models in Xcos and apply parameters through Scilab. Analyse and present output results.

| Reassessment Requirement Type |
Resit arrangements are explained by the following categories;
RC1: A resit is available for both* components of the module.
RC2: No resit is available for a 100% coursework module.
RC3: No resit is available for the coursework component where there is a coursework and summative examination element.
* ‘Both’ is used in the context of the module having a coursework/summative examination split; where the module is 100% coursework, there will also be a resit of the assessment
