Calculate the extrusion force necessary the original length


(a) AA-1100 aluminium 10 cm billets are cold extruded to a round bar of 5 cm diameter. Calculate the extrusion force necessary. The original length of the billet is 500 mm.

(b) If the extrusion ram of the press of part (a) is made of a high strength tool steel with a yield strength of %.2 = 1000 MPa, would it be possible to extrude the 10cm billet to a 5cm diameter bar without deforming the ram? Justify your answer.
