An L-shaped structural section is direct extruded from an aluminum billet in which Lo = 250 mm and Do= 88 rnm. Dimensions of the cross section are given in Figure P19.29. Die angle = 90°. Determine
(a) extrusion ratio,
(b) shape factor, and
(c) length of the extruded section if the butt remaining in the container at the end of the ram stroke is 25 mm.
