The theory of machines and mechanisms is perfect for seniors or post-graduation students in mechanical engineering who are taking courses in kinesiology and/or mechanism dynamics. This book covers the fundamentals of mechanisms, kinematics, and dynamics in machines, taking a theoretical approach, as well as providing several analytic approaches. [Sources: 5]
In Machine Theory, we will explore various types of machine elements, laws, components, transmitters, balances in machines, etc. This is the synthesis of topics from kinematics and dynamics of machines. In the theory of machines, we are going to be dealing with Kinematics and Dynamics. The theory of machines is the branch of engineering science that deals with the study of the relative movements among different parts of the machine, as well as with the forces acting upon it.

The term mechanism is applied to a combination of geometrical bodies which form a machine, or parts of a machine. A machine is a combination of rigid bodies (joints or elements) with the successful constraint of relative motion, used for the transfer of other forms of energy to mechanical energy, or the transfer and modification of available energy for the performance of a certain type of work. A machine is essentially a mechanism or a combination of mechanisms that, in addition to imparting movement to parts, transmits and modifies available mechanical energy to do some sort of desired work. [Sources: 3, 11]
A machine is a device that takes power in some available form and uses that power to perform a certain type of work. The transfer and modification of the energy in a machine require that it include a series of parts (joints or elements) that are selected to make the desired movement and carry safely the forces they are exposed to, for the machine to carry out its tasks successfully. Every machine will be found to consist of a system of parts (links or elements) connected such that, if any is made to move, they all obtain motion, whose relationship to the movement of the first depends on the character of the connections (i.e. Starting from the four types of joints, a rotating joint, slide joint, cam and gear joint, as well as associated connections like cables and belts, a machine can be understood to consist of a collection of substantial parts connecting four types of joints called the mechanism. [Sources: 8, 9, 11]
The components called the elements of a machine, provide structure to the mechanical system and drive its motion. The basic mechanical components of a machine are called machine elements. [Sources: 8]
The Theory of Machines, known simply as TOM, is another major topic of mechanical engineering; it deals with the movement of the body and its associated forces. The theory of Machines and Mechanisms provides a basis for the study of the movement, speed, acceleration, and the static and dynamic forces required to properly design mechanical links, cams, and gear systems. The Kinematics of machines is the study of movement geometry (i.e., displacements, velocities, and accelerations of parts of machines). This kinetics study deals with inertia forces that result from the combined effects of the mass and movement of machine parts. [Sources: 1, 2, 5, 6]
Such transformations are only possible if we are conscious of the connections, the kinematics, the devices, and the parts that are responsible for converting motions (such as gears, train gears), etc. Thus, Theoretical machinery is a key topic in this study. [Sources: 2]
The mechanisms it produces educate students in the history and theory of mechanics. It is also helpful to students taking courses in kinesiology and dynamics of machines. [Sources: 4, 7]
It is focused on the latest developments of the newest mechanisms in kinematics. The theory of machines starts from a detailed background and then goes on to cover topics such as the kinematic analysis of plane mechanisms, dimensional syntheses of connections, etc. Other technical topics such as control mechanisms and the action of the machines on gyroscopes are discussed in detail as well. Mechanisms and machine theory cover both the kinetic and the kinematic aspects, describing the fundamental principles for the analysis and the synthesis of machines. [Sources: 0, 4]
Mechanisms are the branch of scientific analysis that deals with movement, time, and forces, known as mechanisms. The second method involves studying the relative movements of different parts of the mechanism, not considering the forces that cause the movement of parts. Mechanisms and Mechanism Theory goes further and includes such major topics as fluid dynamic friction, balances on rotating parts, and balancing machines. [Sources: 4, 9, 11]
