6. An annealed copper strip 9 in. (228 mm) wide and 1.00 in. (25 mm) thick is rolled to a thickness of 0.80 in. (20 mm) in one pass. The roll radius is 12 in. (300 mm), and the rolls rotate at 100 rpm. Please note that the annealed copper has a true stress of about 12,000psi in the unstrained condition and the true stress reaches to 40,000psi at the end of rolling operation. Calculate the roll force and the power required in this operation. Note that the annealed copper has a true stress of about 12,000 psi in the unstrained condition, and at a true strain of 0.223, the true stress is 40,000 psi.
