A cylinder of metal which is originally 240 mm tall and 80 mm in diameter must be forged to give a cylinder 100 mm in height. The strength coefficient is 250 MPa, and the work hardening exponent is 0.2. (a) Calculate the true stress required to successfully complete the forging operation, assuming that there are no strain rate effects and that friction with the tooling has no effect on the required stress. (1 point) (b) What is the final diameter of the cylinder
