1. Two thick slabs of 300mm each, the first one is used in cold rolling where u=0.08 while the second is used in cold rolling where u-0.5. The mill roll diameter in each case is the same as 600mm. Determine the max draft (reduction) in both cases. Discuss the wide difference in results. 2. A tensile specimen of the metal of 100 mm is length stretched to a length
