Please give answers to both of these parts, thanks (a) Manufacturing is “ the transformation of materials into items of greater value by means of one or more processing and/or assembly operations”. Elaborate on this statement (b) It is not possible to conduct a rolling process without friction. Explain this statement.

A 200 mm wide and 42.0 mm thick plate made of low carbon steel is to be reduced in one pass in a rolling operation. As the thickness is reduced, the plate widens by 4%. The entrance speed of the plate is 15.0 m/min. The roll radius is 325 mm and the rotational speed is 49.0 rev/min. i. If the current horsepower of the available rolling machine is 950 HP, how much thickness could the machine reduce the plate thickness to? ii. If the required thickness needs to be 34.0mm, how could the original width of the plate be changed in order to use the same machine?

A 40 mm thick plate made from 410 grade stainless steel is to be reduced to 34 mm in one pass in a rolling operation. As the thickness is reduced, the plate widens by 3%. The entrance speed of the plate is 13 m/min and the roll radius is 310 mm with a rotational speed of 30 rpm. 5.1 Calculate the minimum coefficient of friction required, that will make the rolling operation possible. 5.2 Calculate the exit velocity of the plate. 5.3 Calculate the forward slip. 5.4 If the final width of the sheet is 200 mm, calculate the required roll force. 5.5 Explain what is roll flattening, its effects and how it can be reduced.
