In discussing the tensile strength can not be separated from the stress and strain. Both of these properties were measured during a tensile or pressure. In the pull, strain is the length of the material, while the press is pemendekkan of material are pressed.
Results of the stress and strain if the share will yield a Young’s modulus (E). Young Mudulus is only valid in the area of the elastic properties of the material.

One thing to note that is a result of the tensile force that occurs is a reduction in diameter as seen in Figure 2.7 below:
