A low-carbon steel plate is 270 mm wide and 25 mm thick. It is reduced in one pass in a two‑high rolling mill to a thickness of 20 mm. Roll radius = 300 mm, and roll speed = 30 m/min. Strength coefficient = 500 MPa, and strain hardening exponent = 0.25. Determine (a) roll force, N (b) roll torque, N-m and (c) power required to perform the operation kW.
