Beginning with its fundamentals the subject has been developed systematically and logically with the emphasis on the physical explanation supported adequately by mathematical formulation. The clarity and systematic representation will make the book intelligible to a beginner. Solved Problems have been inserted at appropriate places to illustrate applications of theoretical principles. In Mechanics the topic of Motion is added, it will give the students an ability to demonstrate Newton’s laws of motion and methods to explain how to apply these laws in a problem. In the topic Work and Energy the conservation of energy is explained systematically. In Fluid Mechanics, concept of turbulent flow and steady flow are discussed in detail.
