Specifying how stress and strain are to be measured, including directions, allows for many types of elastic moduli to be defined. The four primary ones are: 1. (E) describes tensile and compressive , or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of to . It is often referred to simply as the elastic modulus. [pdf]

The instrumentation of a DMA consists of a such as a , which measures a change in voltage as a result of the instrument probe moving through a magnetic core, a temperature control system or furnace, a drive motor (a for probe loading which provides load for the applied force), a drive shaft support and guidance system to act as a guide for the for. We can use dynamic mechanical analysis to measure the modulus of the material. Instead of continuously moving all the way through the linear elastic region, beyond which Hooke's law breaks down, we carefully keep the sample in the Hookean region for the entire experiment. [pdf]
