For instance, the DSR makes it possible for product designers to produce tooth paste with the right consistency to ensure that it can be squeezed from a tube but not diminish the toothbrush. The DSR tests binder placed in between two identical plates concerning the dimension of a quarter. Among home plates actions and the maker determines the viscoelastic properties of the asphalt.
