Drawing: A round rod of annealed 302 stainless steel (K = 1300 MPa and n = 0.3) is being drawn from a diameter of 15 mm to a diameter of 12 mm at a speed 0.25 m/s, using a semidie angle of 8°. a. Calculate the percentage reduction, the applied force due to ideal deformation, friction, and inhomogeneous deformation. Assume coefficient of friction of 0.1. b. Calculate the required power, process efficiency, and the die pressure at the exit.
