An indirect extrusion process starts with an aluminum billet with diameter = 2.0 in and length = 3.0 in, Final cross section after extrusion is a square with 1.0 in on a side. The die angle = 90°. The operation is performed cold and the strength coefficient of the metal K = 26,000 lb/in² and strain hardening expo-nent n = 0.20. In the Johnson extrusion strain equation, a = 0.8 and b= 1.2.

(a) Compute the extrusion ratio, true strain, and extrusion strain.

(b) What is the shape factor of the product?

(c) If the butt left in the container at the end of the stroke is 0.5 in thick, what is the length of the extruded section?

(d) Determine the ram pressure in the process.
