As an example, the DSR allows product designers to create tooth paste with the ideal consistency so that it can be squeezed from a tube yet not diminish the toothbrush. The DSR examinations binder put in between 2 parallel plates concerning the dimension of a quarter. One of the plates moves and the equipment determines the viscoelastic buildings of the asphalt.
