Material Science Lab. IE2210 Abstract we will study the tensile strength of 3 different kinds of polymers (LDPE,HPDE,PVC). This experiment is similar to experiment number 1 but the difference between them that here we are studying tensile properties for polymers and the first one was for metals. We will compare between them and specifies the general principles for determining the tensile properties of plastics under defined conditions. Introduction Chemically, polymers are long-chain molecules of very high molecular weight, often measured in the hundreds of thousands. For this reason, the term “macromolecules” is frequently used when referring to polymeric materials. The trade literature sometimes refers to polymers as resins, an old term that goes back before the chemical structure of the long chains was understood. The first polymers used were natural products, especially cotton, starch, proteins, and wool. Beginning early in the twentieth century, synthetic polymers were made. The first polymers of importance, Bakelite and nylon, showed the tremendous possibilities of the new materials. However, the scientists of that day realized that they did not understand many of the relationships between the chemical structures and the physical properties that resulted. The research that ensued forms the basis for physical polymer science. The principle of the tensile test is the resistance of a material to a
