Mechanics of Materials is generally the name applied to a discipline in which the stress, strain and deflections of loaded structural elements are considered. For nearly all design work it is necessary to know something of the elastic and, often, plastic properties of the material to be used. While these properties are often available from handbooks, sometime particular properties of less common materials is needed, in which case the engineer must perform his own tests. The performance of these typical tests in laboratory will give a better understanding and significance of various material and their properties.
