This book covers the fundamental concepts of work study and ergonomics in a single volume. It discusses the theories of human physiology and cognitive sciences, and evaluates the application of these theories to design a work environment that optimizes work potential and reduces threats of work-related disorders. It provides strategies to design effective work processes and a congenial work environment in order to enhance human well-being and efficiency. The book also explains the ergonomic tools and techniques including biomechanics, work posture assessment tools, anthropometry and work physiology. Using live examples from the industry, the author discusses the principles of work study including string diagram, method study, work sampling and man-machine system. The book demonstrates why it is important to 'fit the job to the man' rather than continuing with conventional practices that 'fit the man to the job'.
This student friendly and self-explanatory textbook attempts to help readers, engineering students in India, grasp the basic concepts of engineering drawing clearly and easily. Care has been taken to include topics that mesh well with the syllabi of most universities, colleges and polytechnic institutes in India. Important topics, such as projection of solids, auxiliary projections, section of solids, isometric projections, orthographic projections and projection of planes, have been discussed comprehensively. Heavy emphasis has also been put on the actual figures described in the text, both from the first angle and third angle projection methods. A chapter on computer graphics further integrates these concepts with modern manual computer aided design. Finally, hundreds of solved examples, practice problems and objective-type questions with answers have been added to ensure the learning objectives of each chapter have been achieved.
