Structures / Materials SectionPage 1 CIVL 1101 -- civil Engineering Structures and IntroductionMechanics of Materials is a branch of applied mechanics that deals with the behavior ofsolid bodies subjected to various types of loading. This field of study is known by severalnames, including Strength of Materials and mechanics of deformable bodies. The solidbodies considered in this book include axially loaded members, shafts in torsion, thin shells,beams, and columns, as well as Structures that are assemblies of these components. Usuallythe objectives of our analysis will be the determination of the stresses, strains, and deflectionsproduced by the loads. If these quantities can be found for all values of load up to the failureload, then we will have a complete picture of the mechanical behavior of the thorough understanding of mechanical behavior is essential for the safe design of allstructures, whether buildings and bridges, machines and motors, submarines and ships, orairplanes and antennas.
CIVL 1101 --Civil Engineering Measurements Page 3 Figure 1. Bar in tension. L P x P P a a P a a d cross-sectional area A of the bar. Furthermore, from the equilibrium (balancing of forces) of the body shown in Figure 1, it is also evident that this resultant must be equal in magnitude and opposite in direction to the applied loadP. Hence, we ...
