As an example, the DSR makes it possible for item developers to create tooth paste with the right consistency to ensure that it can be squeezed from a tube but not diminish the toothbrush. The DSR examinations binder placed in between 2 parallel plates regarding the dimension of a quarter. Among the plates actions and the maker gauges the viscoelastic residential or commercial properties of the asphalt.
