Angle Subtended by Neutral Point Solution

STEP 0: Pre-Calculation Summary

Formula Used

Angle subtended at Neutral Point = sqrt(Thickness after Rolling/Roller Radius)*tan(Factor H at Neutral Point/2*sqrt(Thickness after Rolling/Roller Radius))
φ_n = sqrt(h_fi/R)*tan(H_n/2*sqrt(h_fi/R))
This formula uses 2 Functions, 4 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Angle subtended at Neutral Point - (Measured in Radian) - The angle subtended at neutral point refers to the maximum attainable angle between the roll radius at the first contact and the roll centers during rolling of metals.
Thickness after Rolling - (Measured in Meter) - Thickness after Rolling is the final thickness of the workpiece after the rolling process.
Roller Radius - (Measured in Meter) - The Roller Radius is the distance between the center and the point on the circumference of the roller.
Factor H at Neutral Point - Factor H at Neutral Point is used in rolling calculations to account for the interaction between the material, the rollers, and the deformation process.

STEP 1: Convert Input(s) to Base Unit

Thickness after Rolling: 7.2 Millimeter --> 0.0072 Meter (Check conversion here)
Roller Radius: 102 Millimeter --> 0.102 Meter (Check conversion here)
Factor H at Neutral Point: 2.617882 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

φ_n = sqrt(h_fi/R)*tan(H_n/2*sqrt(h_fi/R)) --> sqrt(0.0072/0.102)*tan(2.617882/2*sqrt(0.0072/0.102))

Evaluating ... ...

φ_n = 0.0963101084825006

STEP 3: Convert Result to Output's Unit

0.0963101084825006 Radian -->5.51816274049543 Degree (Check conversion here)

FINAL ANSWER

5.51816274049543 ≈ 5.518163 Degree <-- Angle subtended at Neutral Point

Angle Subtended by Neutral Point Formula

LaTeX Go

Angle subtended at Neutral Point = sqrt(Thickness after Rolling/Roller Radius)*tan(Factor H at Neutral Point/2*sqrt(Thickness after Rolling/Roller Radius))
φ_n = sqrt(h_fi/R)*tan(H_n/2*sqrt(h_fi/R))

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.
