When a material is being rolled, the perpendicular force on the arc is called what?

(a) Thickness force

(b) Roll force

(c) Angle force

(d) Die force

I got this question in a national level competition.

My doubt stems from Flat Rolling topic in chapter Forming Process of Casting-Forming-Welding II

Correct answer is (b) Roll force

Easiest explanation: There is a force perpendicular to the arc which is in contact when the rolls are pressurizing the material. This force is called a roll force.
