1. Mechanics of Materials(ME-294) Mechanics is the branch of physics that is concerned with the analysis of the action of forces on matter or material systems

2. Mechanics of materials is a branch of applied mechanics that deals with the behavior of solid bodies subjected to various types of loading. The solid bodies considered include: Bars with axial loads Shafts in torsion Beams in bending Columns in compression Other names for this field of study are ▫ Strength of materials ▫ Mechanics of deformable bodies Introduction:

3. Objective: The principal objective of mechanics of materials is to determine the stresses, strains, and displacements in structures. ▫Study of mechanics of materials will provide the future engineer with the means of analyzing and designing various load bearing structures. ▫Both the analysis and design of a given structure involve the determination of stresses and deformations.

4. Applications: Engineering structures and machines, such as airplanes, automobiles, bridges, spacecraft, buildings, electric generators, gas turbines, and so forth, are usually formed by connecting various parts or members. In most structures or machines, the primary function of a member is to support or transfer external forces (loads) that act on it, without failing. Failure of a member may occur when it is loaded beyond its capacity to resist fracture, general yielding, excessive deflection, or instability. These types of failure depend on the nature of the load and the type of member. In elementary mechanics of materials, members subjected to axial loads, bending, moments, and torsional forces are studied.
