For example, the DSR enables product designers to develop tooth paste with the appropriate uniformity so that it can be pressed from a tube yet not diminish the toothbrush. The DSR examinations binder put between 2 parallel plates about the dimension of a quarter. One of the plates moves and the machine gauges the viscoelastic residential properties of the asphalt.
