# Undergraduate Course: Dynamics 3 (MECE09008)

 School School of Engineering College College of Science and Engineering Credit level (Normal year taken) SCQF Level 9 (Year 3 Undergraduate) Availability Available to all students SCQF Credits 10 ECTS Credits 5 Summary The course is designed to allow students to achieve competence in the methods of dynamic analysis for lumped parameter linear systems, covering dynamic response and vibration analysis and, their uses in engineering applications. Course description Many human activities involve mechanical vibrations in different forms. The course provides the tools for evaluating oscillations of real-world mechanical systems. We will investigate rigid body (lumped parameter) linear systems where the dynamic behaviour can be described using one or more spatial coordinates (single and multiple degrees of freedom systems). Students will be able to write the equation of motions of freely vibrating systems or under external exciting force in order to evaluate displacements, frequencies of oscillation, force transmitted and modes of vibration. We will be looking at issues arising from mechanical oscillations in real-world systems (i.e., IC engines, shafts, bridges and high-rise buildings) and devise solutions to minimise (or maximise!) mechanical vibrations. MATLAB will be used as additional and powerful tool to facilitate the procedure to investigate the mechanical oscillations of the studied systems.
