(a) Make a neat sketch of the roll-pressure distribution in flat rolling with powered rolls,

(b) Assume now that the power to both rolls is shut off and rolling is taking place by front tension only, i.e., Steckel rolling. Superimpose on your diagram the new roll pressure distribution, explaining your reasoning clearly

(c) After completing part (b), further assume that the roll bearings are becoming rusty and deprived of lubrication although rolling is still taking place by front tension only. Superimpose a third roll-pressure distribution diagram for this condition, explaining your reasoning.
