Stiffness of Bolt given Thickness of Parts Joined by Bolt Solution

STEP 0: Pre-Calculation Summary

Formula Used

Stiffness of Bolt = (pi*Nominal Bolt Diameter^2*Modulus of Elasticity of Bolt)/(4*Total Thickness of Parts Held Together by Bolt)
k_b' = (pi*d^2*E)/(4*l)
This formula uses 1 Constants, 4 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Stiffness of Bolt - (Measured in Newton per Meter) - The Stiffness of Boltt is the extent to which the bolt resists deformation in response to an applied force.
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.
Modulus of Elasticity of Bolt - (Measured in Pascal) - Modulus of Elasticity of Bolt is a quantity that measures the bolt's or substance's resistance to being deformed elastically when stress is applied to it.
Total Thickness of Parts Held Together by Bolt - (Measured in Meter) - The Total Thickness of Parts held together by Bolt is the sum of the thickness of the parts held together by a bolt.

STEP 1: Convert Input(s) to Base Unit

Nominal Bolt Diameter: 15 Millimeter --> 0.015 Meter (Check conversion here)
Modulus of Elasticity of Bolt: 207000 Newton per Square Millimeter --> 207000000000 Pascal (Check conversion here)
Total Thickness of Parts Held Together by Bolt: 115 Millimeter --> 0.115 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

k_b' = (pi*d^2*E)/(4*l) --> (pi*0.015^2*207000000000)/(4*0.115)

Evaluating ... ...

k_b' = 318086256.175967

STEP 3: Convert Result to Output's Unit

318086256.175967 Newton per Meter -->318086.256175967 Newton per Millimeter (Check conversion here)

FINAL ANSWER

318086.256175967 ≈ 318086.3 Newton per Millimeter <-- Stiffness of Bolt
