The present multicolor edition has been throughly revised and brought up-to-date.Multicolor pictures have been added to enhance the content value and to give the students an idea of what he will be dealing in reality,and to bridge the gap between theory and practice.this book ahs already been include in the 'suggested reading'for the A.M.I.E.(India)examinations.

The academic course of Machine Design Elements and Assemblies (a.k.a. "Machine Design," "Mechanical Engineering Design," etc.) is based on the fundamentals of several different core disciplines, and should prepare students to meet challenges associated with solving real-life mechanical engineering design problems commonly found in industry. Other works focus primarily on verifying calculations of existing machine elements in isolation, while this textbook goes beyond and includes the design calculations necessary for determining the specifications of elements for new assemblies, and accounting for the interaction between them. Machine Design Elements and Assemblies addresses the design considerations associated with the functionality of a full assembly. Most chapters end with a design project that gets progressively more complex. Numerous reviews of prerequisite materials are purposely not included in this title, resulting in a more concise, more practical, and far less expensive product for students, engineers, and professors. Rounding out this incredible package are 120 problems and answers that can be assigned as homework. And nearly 400 additional problems are available on the book's affiliated website, www.machinedesignea.com.

Design is defined as a creative physical realization of theoretical concepts. An electric machine is an electro-mechanical energy conversion device, which converts mechanical energy into electrical energy and vice versa. When the machine converts mechanical energy into electrical energy it is called as generator. When the machine converts electrical energy into mechanical energy it is called as motor. A part of energy is converted to heat. This energy is lost and cannot be recovered. An electrical machine can be designed to operate either as a generator or as a motor.
