Find the extrusion pressure for the metal having extrusion constant 5*109. The initial and final cross-sectional area is 50 mm2 and 10 mm2?

Find the extrusion pressure for the metal having extrusion constant 5*109. The initial and final cross-sectional area is 50 mm2 and 10 mm2? Correct Answer 402 kN

The extrusion pressure is given by: -> P=kAiln(Ai/Af) -> P=5*109* 50*10-6*ln(50/10) -> P=402.35*103 -> P=402 kN.
