A copper billet 150 mm in diameter and 325 mm long is extruded at 1123 k at a speed of 300 m/s. Using square dies and assuming poor lubrication, estimate the force required in this operation if the extruded diameter is 75 mm, where strength coefficient c= 240 mpa and strain rate sensitivity coefficient m=0.06.
