A cold rolling operation is to be used to reduce a 50 mm thick and 200 mm wide copper plate. The entering velocity of the plate is 15 m/min and the exit velocity is 18 m/min. The coefficient of friction is 0.2 and assuming that the reduction in thickness during this process is the maximum draft permissible. If the plate widens by 5% after rolling, calculate the power required to drive the rolls. Assume average flow stress of the material as 180 MPa.
