Question

Deformation process in which work thickness is reduced by compressive forces exerted by two opposing rolls is called extrasion. a)- True b)-False

Answer 1

Answer: False

Explanation: The process in which the thickness of a material is reduced with help of two rolls opposing each other it is called as rolling.It is a type of deformation technique that is done on work piece by using compressive forces exerted by rolls working in the opposite direction of reach other. A draft get created in this process which has the difference of initial and final thickness of work piece. Thus, the statement given is false.
