For example, the DSR makes it possible for item designers to produce tooth paste with the ideal consistency to ensure that it can be pressed from a tube yet not drop off the tooth brush. The DSR tests binder placed in between two identical plates about the size of a quarter. One of home plates actions and the maker gauges the viscoelastic buildings of the asphalt.
