2. A rectangular workpiece has the following original dimensions: length = 62 mm, height = 32 mm, and width is very long. It is upset at room temperature by open-die forging with flat dies to a final height of 24 mm with the width dimension unchanged. The metal has a strength coefficient K = 305 MPa, a strain hardening exponent n = 0.37, and coefficient of friction u = 0.3. (a) plot the pressure in the material as a function of x position along the length (b) Calculate the force per unit length from the average pressure
