The theory of strength of Materials was developed over several centuries by a judicious combination of mathematical analysis, scientific observations and experimental results. Ancient structures had been constructed based on thumb rules developed through experience and intuition of their builders. A structure designed to carry loads comprises various members such as beams, columns and slabs. It is essential to know the load carrying capacity of various members of structure in order to determine their dimensions for the minimum rigidity and stability of isolated structural members such as beams and columns. The theory of strength of materials is presented in this book in a systematic way to enable students understand the basic principles and prepare themselves to the tasks of designing large structures and systems subsequently. It should be appreciated that even awe inspiring structures such as bridges, high rise towers tunnels and space crafts, rely on these principle of their analysis and design HISTORICAL REVIEW Though ancient civilizations could boast of several magnificent structures, very little information is available on the analytical and design principles adopted by their builders. Most of the developments can be traced to the civilizations of Asia, Egypt, Greece and Rome.Greek philosophers Aristotle (384-322 BC) and Archimedes (287 ? 212) who formulated significant fundamental principles of statics. Though Romans were generally excellent builders, they apparently had little knowledge about stress analysis. The strength of materials were formulated by Leonardo da Vinci (AD 1452 ? 1549, Italy) arguably the greatest scientist and artist of all times. It was much later in the sixteenth century that Galileo Galilei ( AD 1564 ? 1642, Itlay) commenced his studies on the strength of materials and behavior of structures. Robe Hooke (1635 ? 1703) made one of the most significant observations in 1678 that materials displayed a certain relation between the stress applied and the strain induced. Mariotte (1620 ? 1684), Jacob Bernoulli (1667 ? 1748), Daniel Bernoulli (1700 ? 1782), Euler (1707 ? 1783), Lagrange (1736 ? 1813), Parent (1666 ? 1748), Columb (1736 ? 1806) and Navier (1785 ? 1836), among several others made the most significant contributions. The first complete elastic analysis for flexure of beams was presented by Columb in 1773 but his paper failed to receive the attention it deserved until 1825 when Navier published a book on strength of materials. Rapid industrial growth of the nineteenth century gave a further impetus to scientific investigations; several researchers and scientist advanced the frontiers of knowledge to new horizons. The simple theories formulated in the earlier centuries have been extended to complex structural configuration and load conditions. Engineers are expected not only to design but also to check the performance of structures under various limit states such a s collapse, deflection and crack widths. The emphasis is always on safety, economy, durability, nevertheless..........
