Overview
DescriptionThe objectives of this subject are to give students an understanding of the kinematics and dynamics of rigid bodies in general planar motion, which is typically encountered in design and analysis of mechanical systems, and an elementary understanding of the vibration of mechanical systems, in particular the dynamic behaviour of singledegreeoffreedom mechanical systems with various damping and applied forces. Students should be able to: model problems in rigid body planar and spatial kinematics and rigid body planar dynamics; understand energy methods in contrast to direct applications of Newton's second law of motion for setting up a model; understand the physics of a problem formulated from a real mechanical system; appreciate the role of vibration in machines and structures in the engineering world; understand the procedures required to evaluate a vibration problem; and analyse the dynamic response of singledegreeoffreedom mechanical systems. The subject also covers the concept of a rigid body, full nomenclature used in kinematics, twobody velocity equations and velocity diagrams of planar motion; twobody acceleration equations and acceleration diagram; threebody velocity equations and acceleration equations including Coriolis acceleration term; angular velocity acceleration equations including threedimensional problems; F=ma applied to a rigidbodydynamics, significance of 'centre of mass', the 'moment' relationship (M=Ia, etc.); angular momentum, conservation of angular momentum (general case, centre of mass moving, no 'fixed' point); linear and angular impulse problems; energy methods for general planar motion; elementary principles of vibration theory, free vibration of undamped singledegreeoffreedom system; free decay vibration of damped singledegreeoffreedom system; and the forced vibration of singledegreeoffreedom system.Subject objectivesUpon successful completion of this subject students should be able to:1. Illustrate basic mechanics concepts such as rigid body, force, motion, work, energy, power, impulse and momentum, and the relationships between them2. Break down a simple machine or a mechanical system into a series of rigid bodies and evaluate the kinematics and kinetics between them3. Apply velocity and acceleration equations of a rigid body in planar motion for determining its motion status, including angular velocity and acceleration, and linear velocity and acceleration of its any given points4. Explain Newtonian mechanics, the relationships between the forces/moments and accelerations of a rigid body in planar motion; the velocities and work, & energies of a rigid body, or rigid bodies; and the relationships between linear/angular momentums and impulses5. Apply the above kinematics and kinetics theories to model and quantify the various physical processes such as a rigid body?s dynamic states at each instant in relation to external forces, the state changes between two instants and impact problems between rigid bodies. (These are the core activities of practical mechanical engineering work.)This subject also contributes specifically to the development of the following course intended learning outcomes:Apply systems

fully in your group for any group projects.NOTE: As an indication, a typical 6cp subject would normally assume a total time commitment (including class time) of approximately 150 hours, for an average students aiming to pass the subject).ContentThe subject contents are:revision on the kinematics of particles;the kinematics of rigid bodies including absolute velocity and acceleration of rigid bodies in translation, fixed axis rotation, and general planar motions, concepts of velocity pole and introduction to spatial kinematics;kinetics of rigid bodies including the relationships between forces
