• A cylindrical billet that is 100 mm long and 40 mm in diameter is reduced by indirect (backward) Extrusion to a 15 mm diameter. Die angle = 90°. If the Johnson equation has a = 0.8 and b = 1.5, And the flow curve for the work metal has K = 750 MPa and n = 0.15, determine: (a) extrusion Ratio, (b) true strain (homogeneous deformation), (c) extrusion strain, (d) ram pressure, and (e) ram force.
