A 42 mm thick plate made of low carbon steel is to be reduced to 34 mm in one pass in a rolling operation. As the thickness is reduced, the plate widens by 4%. The yield strength of the steel plate is 174 MPa and the tensile strength is 290 MPa. The entrance speed of the plate is 15 m/min. The roll radius is 325 mm and the rotational speed is 49 rev/min. Determine: i) the minimum required coefficient of friction that would make this rolling operation possible ii) the exit velocity of the plate iii) the forward slip
