A 2.00” diameter billet will be reduced in diameter to 1.00”
using direct extrusion as shown below. The strength coefficient and
strain hardening exponent of the material are K = 60,000 lb/in2 and
n = 0.18. The coefficients for Johnson’s strain formula are a = 0.8
and b = 1.5. The ram force available on the extrusion press is 1.75
X 10^6 lb. Calculate the maximum length (Lmax) of billet that can
be extruded.
