Question

Three cross-sections are extruded using a horizontal extrusion press. The first is a square of side 3 inches, the second is an equilateral triangle of side 4 inches and the third is a circle of radius 3 inches. Calculate the CCD for each cross-section. Determine the shape factor for each cross-section. If the original billet is of 8 inches diameter, calculate the extrusion ratio for each case. Determine the extrusion constant at a temperature of 1250 degrees F for 70/30 Brass. Use that constant to determine the hot extrusion force
