### Angle subtended by Neutral point Formula

angle_neutral_point = (sqrt(Thickness after Rolling/Radius of Rollers)*tan((Factor H at Neutral point/2)*sqrt(Thickness after Rolling/Radius of Rollers)))*(pi/180)
φN = (sqrt(h/R)*tan((HN/2)*sqrt(h/R)))*(pi/180)

## What is Neutral point ?

Neutral point is that point where there is no slip between the work piece and the rolls and frictional forces between material and rollers are in equilibrium. To identify the neutral plane position, the two expressions for the roll pressure p– and p+ should be equated as the pressures from both ends peak at the neutral plane. As at entry the material is pulled in and roller is moving faster than material, but at exit material is pulled back and roller is moving slower than material.
