The motion of all vehicles requires the expenditure of a certain quantity of mechanical energy, and in motor vehicles the system that supplies such energy (in most cases an internal combustion engine) is on board. The lack of an adequate prime mover is the main reason that mechanical vehicles could be built only at the end of the industrial revolution, and enter mass production only in the Twentieth Century, in spite of attempts dating back to ancient times. For a mechanical vehicle to be built, a prime mover able to move not only itself, but the vehicle structure and payload...
This publication deals primarily with small and medium-sized induction motors which are the most common type of alternating current motor. The combination of new materials and more sophisticated methods for calculation, design and production have made the modern three-phase induction motor a robust and reliable prime mover.

Practically every industrial process requires objects to be moved, manipulated or be subjected to some form of force. This is generally accomplished by means of electrical equipment (such as motors or solenoids), or via devices driven by air (pneumatics) or liquids (hydraulics).
This manual covers the various types of auxiliary power generating systems used on military installations. It provides data for the major components of these generating systems; such as, prime movers, generators, and switchgear. It includes operation of the auxiliary generating system components and the routine maintenance which should be performed on these components. It also describes the functional relationship of these components and the supporting equipment within the complete system.
Flexible Machine Elements
Belt drives are called flexible machine elements. Flexible machine elements are used for a large number of industrial applications, some of them are as follows. 1. Used in conveying systems Transportation of coal, mineral ores etc. over a long distance 2. Used for transmission of power. Mainly used for running of various industrial appliances using prime movers like electric motors, I.C. Engine etc.
In common usage, an engine burns or otherwise consumes fuel, and is differentiated from an electric machine (i.e., electric motor) that derives power without changing the composition of matter. A heat engine may also serve as a prime mover, a component that transforms the flow or changes in pressure of a fluid into mechanical energy. An automobile powered by an internal combustion engine may make use of various motors and pumps, but ultimately all such devices derive their power from the engine....
III. ECONOMICS AND THE REVOLT AGAINST REASON 1. The Revolt Against Reason
is true that some philosophers were ready to overrate the power of human reason. They believed that man can discover by ratiocination the final causes of cosmic events, the inherent ends the prime mover aims at in creating the universe
But also contributed a great deal to the conceptual development of the grammar. Last but far from least, we express our gratitude to Delia Summers, the Director of Longman Dictionaries, as prime mover of this project who, at a time when the idea was as strange to us as to the rest of the world, inspired us to plan a truly corpus-based grammar, and persuaded us to turn that vision into a reality.
Positioning systems in general have their most basic form, and also the most complex, in the human being. The brain serves as the summing network that accepts the command for a desired motion or position, the musculatory system serves as the power source or prime mover to cause motion to take place, and the sensory system, such as the eyes, determines the present position. In general, these three things—the brain, the muscles, and the eyes—are analogues to the three basic parts of any positioning system....

As the literature will attest, traditional command-and-control management is largely derived from the principles
of Frederick Taylor’s “scientific management.” Taylor’s scientific management approach was based in turn on
the seventeenth century science of Newton that saw the world as a vast and magnificently ordered “clockwork
universe” governed by the classical laws of nature. Scientific management is recognized as the prime mover
in lifting the “working masses” in developed countries to new levels of affluence in the 20th
JAMES HARRINGTON, eldest son of Sir Sapcotes Harrington of Exton, in Rutlandshire, was born in the
reign of James I, in January, 1661, five years before the death of Shakespeare. He was two or three years
younger than John Milton.
