Flange pressure given Twisting moment Solution

STEP 0: Pre-Calculation Summary
Formula Used
Flange pressure = 2*Number of Bolts*Twisting Moment/(Area*Torque Friction Coefficient*Diameter of Bolt)
pf = 2*n*Mt/(A*Cu*dbolt)
This formula uses 6 Variables
Variables Used
Flange pressure - (Measured in Pascal) - Flange pressure refers to the pressure exerted onto the flange (a projecting flat rim, collar, or rib on an object, serving for strengthening or attachment).
Number of Bolts - Number of Bolts is simply defined as the number of bolts that are under our consideration.
Twisting Moment - (Measured in Newton Meter) - Twisting moment is defined as when we twist the end of the bar either clockwise or counterclockwise then bending moment will form.
Area - (Measured in Square Meter) - Area is the space occupied by a flat surface or the shape of an object.
Torque Friction Coefficient - Torque Friction Coefficient are values based on friction coefficients of 0.12 between threads and 0.14 between nut and washer or head and washer, as manufactured.
Diameter of Bolt - (Measured in Meter) - The Diameter of Bolt is a chord that runs through the center point of the circle.
STEP 1: Convert Input(s) to Base Unit
Number of Bolts: 3 --> No Conversion Required
Twisting Moment: 13 Newton Meter --> 13 Newton Meter No Conversion Required
Area: 100 Square Millimeter --> 0.0001 Square Meter (Check conversion here)
Torque Friction Coefficient: 0.14 --> No Conversion Required
Diameter of Bolt: 9 Millimeter --> 0.009 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
pf = 2*n*Mt/(A*Cu*dbolt) --> 2*3*13/(0.0001*0.14*0.009)
Evaluating ... ...
pf = 619047619.047619
STEP 3: Convert Result to Output's Unit
619047619.047619 Pascal -->619.047619047619 Megapascal (Check conversion here)
FINAL ANSWER
619.047619047619 ≈ 619.0476 Megapascal <-- Flange pressure
