Module Outline

Have you ever ask yourselves why objects break? It happens in nature and every area of human activity and to answer this question we have to look not only at the shape of the object and the loads acting on it but also deep inside it, at the structure of the materials, the strength of the bonds between the particles making it, the purity of the material and many other factors. In Newtonian Mechanics we looked at the objects from an outside perspective. In This Strength of Materials we look at what happens inside it, at the internal forces which are developed and which react to the external loading. To do this effectively and efficiently we introduce and use the concepts of stress and strain.
The engineer nowadays can use software packages as tools for solving complex problems related to the strength and physical performance of mechanical parts and assemblies. No matter how convenient these tools are, they cannot replace the simple, analytical calculations of stresses and deflections, which are the object of study of Strength of Materials. This discipline introduces fundamental concepts, which allow the student to understand the physical phenomena that take place when materials are under the action of forces. By mastering those fundamental concepts one not only is able to carry out quick calculations, but can use more efficiently and even improve the numerical tools aforementioned. These concepts are vital to the mechanical design process and it can be said that without the prediction of the strengths of the parts no mechanical design process can take place.
