As an example, the DSR allows item programmers to produce tooth paste with the right consistency so that it can be pressed from a tube yet not fall off the tooth brush. The DSR tests binder put in between two parallel plates concerning the dimension of a quarter. One of home plates actions and the machine gauges the viscoelastic buildings of the asphalt.
