Today we are doing an interesting experiment to study about the mechanical properties of materials i.e. metals, polymers and ceramics. Before that we need to determine the microstructure of each type of materials to study their different arrangement of atoms. Materials are not in perfect atomic arrangement , meaning there are defects within their structure. This Experiment is useful to study the materials science as part of engineering field of reach and developement.
