Q. Rolling is a forming process in which thickness of the metal plate is decreased by increasing its length.
✅ Correct Answer: (A)
true
Explanation: rolling is a metal forming process in which the metal plate is squeezed between the two hard rollers. in the operation, the thickness is decreased and the length is increased as the volume of the metal is conserved. this method is mainly used for the production of thin metal plates which can be done by performing hot rolling or cold rolling, depending on the required mechanical properties.
