14.3. If about 30 passes are required to reduce a large ingot to a bloom, about what percentage reduction per pass is attained? (Hint: Use Figure 14.3 to estimate the percent reduction for each pass. Plot on graph paper.) 14.4. Sketch a method to extrude a lead sheath on wire cable. 14.5. Design a process for producing square tubing. Sketch the roll system. (Hint: Confine your work to one sheet of engineering paper.) 14.6. What size press is needed to forge an open-end wrench that has a "flat size" cross section of 9.3 in.? 14.7. A 2-in. steel cross section is upset. What is the maxi- mum length that can be upset? 14.8. Sketch five methods for the manufacture of pipe. 14.9. Find the deformation energy in forging a 4-in. OD slug of steel that is 2 in. long. It has a forgeability in- dex= 1.5 and a shape factor 1. Repeat for 5-in. slug that is 2 in. long.
