Brinell Hardness Number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brinell Hardness Number = Load/((0.5*pi*Diameter of Ball Indenter)*(Diameter of Ball Indenter-(Diameter of Ball Indenter^2-Diameter of Indentation^2)^0.5))
BHN = W/((0.5*pi*D)*(D-(D^2-d_i^2)^0.5))
This formula uses 1 Constants, 4 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Brinell Hardness Number - Brinell Hardness Number is a number expressing the load applied in testing in kilograms divided by the spherical area of indentation produced in the specimen in square millimeters.
Load - (Measured in Newton) - Load is the instantaneous load applied perpendicular to the specimen cross section.
Diameter of Ball Indenter - (Measured in Meter) - Diameter of Ball Indenter is the diameter of indenter used for measuring the hardness.
Diameter of Indentation - (Measured in Meter) - Diameter of Indentation is the diameter of the rim of permanent indentation obtained.

STEP 1: Convert Input(s) to Base Unit

Load: 3.6 Newton --> 3.6 Newton No Conversion Required
Diameter of Ball Indenter: 62 Millimeter --> 0.062 Meter (Check conversion here)
Diameter of Indentation: 36 Millimeter --> 0.036 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BHN = W/((0.5*pi*D)*(D-(D^2-d_i^2)^0.5)) --> 3.6/((0.5*pi*0.062)*(0.062-(0.062^2-0.036^2)^0.5))

Evaluating ... ...

BHN = 3208.13347393492

STEP 3: Convert Result to Output's Unit

3208.13347393492 --> No Conversion Required

FINAL ANSWER

3208.13347393492 ≈ 3208.133 <-- Brinell Hardness Number

Beam Shear Stress

Go Beam Shear Stress = (Total Shear Force*First Moment of Area)/(Moment of Inertia*Thickness of Material)

Bending Stress

Go Bending Stress = Bending Moment*Distance from Neutral Axis/Moment of Inertia

Bulk Stress

Go Bulk Stress = Normal Inward Force/Cross Sectional Area

Direct Stress

Go Direct Stress = Axial Thrust/Cross Sectional Area
