The following information is drawn from the official definition of the subject which has been approved by the Faculty Board of Engineering. It will typically remain the same from semester to semester, except where variations are approved by the Faculty Board.
The main objective of the subject is to help the students developing the ability to analyse any mechanics problem in a simple and logical manner and to apply a few, well understood, basic principles to its solution. At the end of this subject, students should have gained an understanding of kinematics and kinetics of rigid bodies, and free vibration of single degree of freedom mechanical systems. The three immediate learning objectives of this subject are: Understanding basic mechanics concepts such as rigid body, force, motion, work, energy, power, impulse and momentum, and the relationships between them; Gaining skills in breaking down a simple machine into a series of rigid bodies and to evaluate the motions of them with forces applied to the system; Acquiring knowledge in Newtonian mechanics, the relationships between the above physical concepts and process, and the solution procedures for determining these relationships, which are the hardware of practical mechanical engineering activity.
Summary of material to be covered
The 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 and motions (Newton’s 2nd law of motion), energy, work, power, principle of energy conservation, linear and angular impulses, and momentums equations; introduction to free vibration of a single degree of freedom mechanical system
