The knowledge of this subject is very essential for an engineer students in designing the various parts of a machine. Theory of machines may be defined as that branch of engineering-science, which deals with the study of relative motion between the various parts of a machine, and forces which act on them. The belts or ropes are used to transmit power from one shaft to another by means of pulleys which rotate at the same speed or at different speeds.

Control engineering is based on the foundations of feedback theory and linear system analysis, and it integrates the concepts of network theory and communication theory. Therefore control engineering is not limited to any engineering discipline but is equally applicable to aeronautical, chemical, mechanical, environmental, civil, and electrical engineering. For example, a control system often includes electrical, mechanical, and chemical components. Furthermore, as the understanding of the dynamics of business, social and political systems increases, the ability to control these systems will also increase.

Course covers fundamentals of calculation of the combination of stresses by different methods, shaft design, stresses in power screw and diameter of rope. It starts with examples of stresses in machine parts. Topics to be covered include belts and flywheel calculation.

This course is intended to be an introductory text in power electronics primarily for the undergraduate electrical engineering student. The student should be acquainted with electronic devices such as diodes and transistors, but the emphasis of this text is on circuit topology and function rather than on devices. Understanding the voltage-current relationships for linear devices is the primary background required, and is also appropriate for junior- or senior-level undergraduate electrical engineering students.
