1.	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 forceI got this question in a national level competition.My doubt stems from Flat Rolling topic in chapter Forming Process of Casting-Forming-Welding II
Answer» 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.
