2. A cylindrical part with a length of 100 mm and a diameter of 50 mm will be reduced to a diameter of 20 mm by extrusion. Mold angle is 90. In the Johnson equation, a = 0.8 and b = 1.4. The yield curve strength coefficient for the work material is 800 MPa and the hardening exponent is 0.13. a) extrusion rate, b) actual strain (homogeneous deformation conditions), c) extrusion strain, for direct and indirect extrusion at block lengths of L = 100 mm and L = 50 mm, d) ram pressure (MPa) and e) Calculate the ram force (kN).
