As an example, the DSR allows product designers to develop tooth paste with the best consistency to make sure that it can be pressed from a tube however not fall off the toothbrush. The DSR tests binder placed in between 2 parallel plates concerning the dimension of a quarter. One of home plates steps and the device gauges the viscoelastic homes of the asphalt.
