MECHANICS OF MATERIAL- CONCEPT OF STRESS

INTRODUCTION
the main study obkective of the mechanics of materials is to provide the future engineer with the means of analyzing and distinguishing various machine and load bearing structure involve the determination of stresses and deformations. Mechanics of materials will deals with the concept of stresses. There are 3 main type of stresses that we will learn:

• normal stresses
• shearing stresses
• bearing stresses

the aim of this subject is to provide foundation knowledge in stresses, strains, and displacements of deform body, produced by the exerted loads.

the basic outcomes of this subject are as follows:

1. define and determine the concept of stress-strain diagram.
2. analyse the deformation of a structural member under axial loading.
3. analyse the transformation of the component of stress and strain.
4. analyse the stresses and strains in prismatic members subjected to bending.
5. analyse the design of beams under traverse loading.
6. analyse the design of vertical prismatic members supporting axial loads.
7. analyse and design of shafts subjected to twisting couples.
8. analyse the stresses and deformations in structures using strain energy.
