A metal strip is to be rolled from an initial wrought thickness of 3.5 mm to a final rolled thickness of 2.5 mm in a single pass rolling mill having rolls of 250 mm diameter. The strip is 450 mm wide. The average coefficient of friction in the roll gap is 0.08. Taking plane strain low stress of 140 MPa, for the metal and assuming negligible spreading, the roll separating force is.....
