# Undergraduate Course: Dynamics 2 (MECE08009)

 School School of Engineering College College of Science and Engineering Credit level (Normal year taken) SCQF Level 8 (Year 2 Undergraduate) Availability Available to all students SCQF Credits 10 ECTS Credits 5 Summary This course aims to provide a basic understanding of the Laws of Newtonian Mechanics for bodies and systems of bodies in plane motion, and to achieve proficiency in their use in conjunction with kinematic principles for a range of mechanical engineering applications. Course description 1. Dynamics of Particles Newton's Laws of Motion and the nature of forces; D'Alembert approach; dynamical laws of single particle; dynamical theorems for systems of particles; Linear and Angular momentum; mass centre properties; motion in polar coordinates; Coriolis acceleration. Central Force motion and orbits. 2. Systems of Bodies Rigid body as a model; dynamical laws for rigid bodies in pure translation, fixed axis rotation and general plane motion; inertia couple; moments of inertia; inertia theorems; rolling versus sliding. Kinematic relations between interacting bodies: circular motion, gear drives, belts and pulleys, rolling on a plane. Applications to coupled systems, power transmission, simple vehicles, rotational unbalance, static and dynamic-balancing of rotors; introduce balancing of reciprocating mechanisms. 3. Work - Energy Approach Kinetic and potential energy; work and power; work-energy theorems applied to system calculations; the conservative system as a special case. 4. Oscillatory Motion Introduction to oscillations; differential equations of translational and rotational SDF systems, free vibration, natural frequency; damping and critical damping; introduction to resonance, features of vibratory phenomena. 5. Gyroscopic Torque Introduction to gyroscopic torque and gyroscopic effects; angular momentum vector of a rotor; precession applications.
