$1.$ A cylindrical workpiece with D$=3\mathrm{.}0,$ H $=3\mathrm{.}5$ is upset forged in an open die to a final thickness of $2\mathrm{.}5.$ The coefficient of friction between the die and workpiece is $0\mathrm{.}2.$ The work material has a strength coefficient K $=30,000$ psi and strain hardening exponent of $0\mathrm{.}15.$ Generate a plot of the instantaneous force as a function of thickness from the $0\mathrm{.}2\%$ strain yield point to the final thickness.

Please Include the Equation for the Plot In Excel
