If the extrusion ratio of the material used is increased by two times, the required extrusion pressure _____________

If the extrusion ratio of the material used is increased by two times, the required extrusion pressure _____________ Correct Answer increases by two times

The extrusion pressure is directly propositional to the extrusion ratio of the material extruded. So, if the extrusion ratio is increased by two times, then the pressure will also increase by two times.
