A cylinder of 100 mm diameter and 400 mm height is subjected to open-die forging to accomplish a reduction in the height to 150 mm at high temperature. Calculate the magnitude of the force required to give this reduction in height if the strain rate is constant at 10 s-1. Assume that the strength constant is 120 MPa and that the strain rate sensitivity exponent is 0.15. Also assume that there is no effect of friction with the tooling and no work hardening. (2 points)
