We have provided all the pdf links to download study material for all the 1st year engineering b. Engineering Mechanics Basics: Engineering mechanics is the application of mechanics to solve problems involving common engineering elements.

The goal of this Engineering Mechanics course is to expose students to problems in mechanics as applied to plausibly real-world scenarios.

This capacity requires more than a mere knowledge of the physical and mathematical principles of mechanics; also required is the ability to visualize physical confi gurations in terms of real materials, actual constraints, and the practical limitations which govern the behavior of machines and structures.

One of the primary objectives in a mechanics course is to help the student develop this ability to visualize, which is so vital to problem formulation. Indeed, the construction of a meaningful mathematical model isoften a more important experience than its solution. Maximum progress is made when the principles and their limitations are learned together within the context of engineering application.

There is a frequent tendency in the presentation of mechanics to use problems mainly as a vehicle to illustrate theory rather than to develop theory for the purpose of solving problems.

When the fi rst view is allowed to predominate, problems tend to become overly idealized and unrelated to engineering with the result that the exercise becomes dull, academic, and uninteresting. This approach deprives the student of valuable experience in formulating problems and thus of discovering the need for and meaning of theory.

The second view provides by far the stronger motive for learning theory and leads to a better balance between theory and application. The crucial role played by interest and purpose in providing the strongest possible motive for learning cannot be overemphasized. Furthermore, as mechanics educators, we should stress the understanding that, at best, theory can only approximate the real world of mechanics rather than the view that the real world approximates the theory.

This difference in philosophy is indeed basic and distinguishes the engineering of mechanics from the science of mechanics. Over the past several decades, several unfortunate tendencies have occurred in engineering education. First, emphasis on the geometric and physical meanings of prerequisite mathematics appears to have diminished. For this reason, computer usage must be carefully controlled. At present, constructing free-body diagrams and formulating governing equations are best done with pencil and paper.

On the other hand, there are instances in which the solution to the governing equations can best be carried out and displayed using the computer. To conserve adequate time for problem formulation, it is suggested that the student be assigned only a limited number of the computer-oriented problems. As with previous editions, this Eighth Edition of Engineering Mechanics is written with the foregoing philosophy in mind.

Engineering Mechanics is written in a style which is both concise and friendly. The major emphasis is on basic principles and methods rather than on a multitude of special cases.
