Using different symbols for casting and wrought alloys, plot ultimate tensile stress as a function of yield strength for the aluminum alloys in Tables 2.7 and 2.8. 4. You have one ton of Fe 2 O 3 iron ore which you will reduce to pure iron. a. How many pounds of C are needed assuming you are 100% efficient at producing CO 2 ? b. How many pounds of iron will you get? 5. You have a cube of liquid that takes five minutes to solidify. a. If each side of the cube is increased 50% in length, how long will it take the cube to solidify? Use equation 3.13. b. If instead , only one dimension of the cube is increased by 50%, how long will it take for the new item to solidify? (all sides are still rectangular or square)...
