m The following text was removed from the initial description of the technique: "..., also known as 'dynamic mechanical spectroscopy')''. The reason for this change is because this statement is inaccurate. "Spectroscopy" refers to a technique which measures different wavelengths of light and their intensities. DMA is a technique that applies forces to a sample and measures deflection (i.e. translational motion); it is therefore not a spectroscopic technique.. |

===Measuring glass transition temperature===
One important application of DMA is measurement of the [[Glass transition#Transition temperature Tg|glass transition temperature]] of polymers. Amorphous polymers have different glass transition temperatures, above which the material will have [[rubber]]y properties instead of glassy behavior and the stiffness of the material will drop dramatically along with
===Polymer composition===
