You are forward extruding a cylindrical copper billet (k=256 mpa, n=0.18; c = 155 mpa, m = 0.15) from a diameter of 0.5 m to a diameter of 0.18 m at a ram speed of 0.4 m/min. the billet is initially 1.5 m long. the extrusion process is performed at a temperature = 850°c. tmelting = 1082°c. the die is flat bottomed. determine the maximum extrusion force.
