In a rolling operation, material A, 8 inches wide, and 2 inches thick was reduced to the maximum extent possible in a single pass. During this reduction, the coefficient of friction was maintained at 0.4 and the center-center distance between the rolls was 16.0 inches. Calculate the length of contact between roll and strip. Calculate the true strain in the roll gap. Calculate the true stress at this value for the above material. Use an average of this stress and the true yield stress to determine the average true stress of the strip in the roll gap. Determine the roll force.

A specimen of material A in a tension test elongates from an original length of 2.2 to a length L uniformly, after which is necking begins. The strength coefficient of the material is given as 120,000 psi, and the strain hardening exponent is 0.5
