Learning Objectives

While reading and after studying this chapter, you will be able to:

• Understand the objectives and the scope of the subject 'Mechanics of Machines'.

• Appreciate the various branches of Mechanics of Machines' subject and their scope.

• Recollect certain fundamental concepts that are required to study the 'Mechanics of Machines' subject.

ABOUT MECHANICS OF MACHINES

• The subject Theory of Machines', also known as 'Mechanics of Machines', comprises:

(i) the study of the relative motion between the parts of a machine, and

(ii) the study of the forces which act on those parts.

• It is understood that most mechanical engineering activities revolve around a mechanical system whose function depends on the relative movements among its various members. The design of a mechanical system needs a proper understanding of: (i) the geometrical aspects of motion, and (ii) the various forces involved in motion. The theory of machines subject tries to provide underlying theories and scientific principles behind the behavioural characteristics of all machines and mechanisms.

• The major objectives of the subject theory of machines are to provide the engineers the necessary tools to systematically synthesize a system which means scientifically arriving at the critical shapes and dimensions of the bodies constituting the system.
