Three cross-sections are extruded using an extrusion press. The first cross section is an isosceles right triangle of perpendicu
lar sides of length 0.5 inch and 1.2 inch. The second is an equilateral triangle of side 1.5 inches, the rectangle of sides 0.9 inch and 1.2 inch. Calculate the CCD for each cross-section. Determine the shape factor for each crosssection. If the original billet is of 4 inches diameter, calculate the extrusion ratio for each case.
