11. a planned extrusion operation involves steel at 800°c, with an initial diameter of 100 mm and a final diameter of 20 mm. two presses, one with a capacity of 20 mn and the other of 10 mn, are available for this operation. obviously, the larger press requires greater care and more expensive tooling. is the smaller press sufficient for the operation? if not, what recommendations would you make to allow use of the smaller press?
