A 3. 0 in thick slab that is 9 in wide is to be reduced in a single pass in a two-high rolling
mill to a thickness of 2. 5 in. The roll has a radius = 15 in, and its speed = 30 ft/min. The
work material has K = 25000 lb/in2 and n = 0. 16. Determine: (a) roll force, (b) roll torque,
and (c) power required to accomplish this operation
