The text introduces and reinforces key principles, concepts, and methods of analysis of the performance of fluid power components and systems. The physical configuration of individual components is presented and this information is supplemented with material relating to dynamic analysis. The principles of analysis have been demonstrated with a comprehensive range of worked examples and with suitable exercises for the student to follow in order to acquire considerable command of fluid power system design details. Some of the ways are shown where fluid power can be used to advantage in engineering systems. Fluid power may often provide a way to transmit power that, for certain levels of power and other circumstances, may be superior to other mechanical or electrical techniques.
