1) What is rolling in the context of the bulk deformation processes?

[helpme]

2). A single pass rolling operation reduces a 20mm thick plate to 18mm.The starting plate is 200mm wide Roll radius = 250 mm and rotational speed = 12rev/min.the work material has a strength coefficient = 600Mpa and a strength coefficient =0.22 determine a).roll force b).roll torque c)power required
please show me all the workigs
