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]
