Wrench Torque Required to Create Required Pre Load Solution

STEP 0: Pre-Calculation Summary
Formula Used
Wrench Torque for Bolt Tightening = 0.2*Pre Load in Bolt*Nominal Bolt Diameter
Mt = 0.2*Pi*d
This formula uses 3 Variables
Variables Used
Wrench Torque for Bolt Tightening - (Measured in Newton Meter) - Wrench Torque for Bolt Tightening is defined as the torque required to create a load on fasteners such as a nut, bolt, or lag screw.
Pre Load in Bolt - (Measured in Newton) - Pre Load in Bolt is the tension created in a bolt when it is tightened.
Nominal Bolt Diameter - (Measured in Meter) - Nominal Bolt Diameter is the diameter equal to the external diameter of the threads or the overall diameter of the part of the bolt.
STEP 1: Convert Input(s) to Base Unit
Pre Load in Bolt: 16500 Newton --> 16500 Newton No Conversion Required
Nominal Bolt Diameter: 15 Millimeter --> 0.015 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Mt = 0.2*Pi*d --> 0.2*16500*0.015
Evaluating ... ...
Mt = 49.5
STEP 3: Convert Result to Output's Unit
49.5 Newton Meter -->49500 Newton Millimeter (Check conversion here)
FINAL ANSWER
49500 Newton Millimeter <-- Wrench Torque for Bolt Tightening
(Calculation completed in 00.004 seconds)

Tensile Force on Bolt in Shear
Go Tensile Force in Bolt = pi*Core Diameter of Bolt*Height of Nut*Shear Yield Strength of Bolt/Factor of Safety of Bolted Joint
Thickness of Parts Held Together by Bolt given Stiffness of Bolt
Go Total Thickness of Parts held together by Bolt = (pi*Nominal Bolt Diameter^2*Modulus of Elasticity of Bolt)/(4*Stiffness of Bolt)
Stiffness of Bolt given Thickness of Parts Joined by Bolt
Go Stiffness of Bolt = (pi*Nominal Bolt Diameter^2*Modulus of Elasticity of Bolt)/(4*Total Thickness of Parts held together by Bolt)
Young's Modulus of Bolt given Stiffness of Bolt
Go Modulus of Elasticity of Bolt = (Stiffness of Bolt*Total Thickness of Parts held together by Bolt*4)/(Nominal Bolt Diameter^2*pi)
Tensile Force on Bolt in Tension
Go Tensile Force in Bolt = pi/4*Core Diameter of Bolt^2*Tensile Yield Strength of Bolt/Factor of Safety of Bolted Joint
Tensile Force on Bolt given Maximum Tensile Stress in Bolt
Go Tensile Force in Bolt = Maximum Tensile Stress in Bolt*pi/4*Core Diameter of Bolt^2
Imaginary Force at Center of Gravity of Bolted Joint given Primary Shear Force
Go Imaginary Force on Bolt = Primary Shear Force on Bolt*Number of Bolts in Bolted Joint
Number of Bolts given Primary Shear Force
Go Number of Bolts in Bolted Joint = Imaginary Force on Bolt/Primary Shear Force on Bolt
Pre Load in Bolt given Amount of Compression in Parts Joined by Bolt
Go Pre Load in Bolt = Amount of Compression of Bolted Joint*Combined Stiffness of Bolt
Pre Load in Bolt given Wrench Torque
Go Pre Load in Bolt = Wrench Torque for Bolt Tightening/(0.2*Nominal Bolt Diameter)
Wrench Torque Required to Create Required Pre Load
Go Wrench Torque for Bolt Tightening = 0.2*Pre Load in Bolt*Nominal Bolt Diameter
Resultant Load on Bolt given Pre Load and External Load
Go Resultant Load on Bolt = Pre Load in Bolt+Load due to External Force on Bolt
Pre Load in Bolt given Elongation of Bolt
Go Pre Load in Bolt = Elongation of Bolt*Stiffness of Bolt

Wrench Torque Required to Create Required Pre Load Formula

Wrench Torque for Bolt Tightening = 0.2*Pre Load in Bolt*Nominal Bolt Diameter
