A cylindrical work part with D=2.5 in and h=2.5 in is upset forged in an open die to a height = 1.5 in. Coefficient of friction at the die–work interface = 0.10. The work material has a flow curve defined by: K= 40,000 lb/in2 and n = 0.15. Yield strength = 15,750 lb/in2. Determine the instantaneous force in the operation (a) just as the yield point is reached (yield at strain = 0.002), (b) at height h = 2.3 in, (c) h = 2.1 in, (d) h = 1.9 in, (e) h = 1.7 in, and (f) h = 1.5 in
