### Basic Concepts Price 2.99  |  2.99 Rewards Points

In any field the importance of a thorough knowledge of fundamentals cannot be over emphasised. Fundamentals have always been stressed in the learning of new skills. Similarly, the mechanics branch of science which deals with the forces and their effect on bodies on which they act is founded on basic concepts and forms the ground-work for further study in the design and analysis of machines and structures. Mechanics can be divided into two parts. (Fig. 1.1) (i) â€˜Staticsâ€™ which relates to the bodies at rest and (ii) â€˜dynamicsâ€™ which deals with bodies in motion. (In mechanics the term strength of materials refers to the ability of the individual parts of a machine or structure to resist loads. It also permits the determination of dimensions to ensure
