A cylindrical specimen made of annealed 1112 steel (strength coefficient k=750 mpa, strain hardening coefficient n=0.15) has a diameter of 225 mm and 125 mm high. It is upset at room temperature, by open die forging with flat dies to a height of 50 mm. Assuming that the coefficient of friction is 0.2, calculate upsetting force required at the end of the stroke. Use average pressure formula.
