The DSR makes it possible for item designers to develop tooth paste with the appropriate uniformity so that it can be squeezed from a tube however not drop off the tooth brush. The DSR examinations binder placed between two parallel plates regarding the dimension of a quarter. Among home plates moves and the equipment gauges the viscoelastic buildings of the asphalt.
