This formula uses 5 Variables
Variables Used
Stiffness of Spring - (Measured in Newton per Meter) - Stiffness of Spring is a measure of the resistance offered by an elastic body to deformation, every object in this universe has some stiffness.
Modulus of Rigidity of Spring Wire - (Measured in Pascal) - Modulus of rigidity of spring wire is the elastic coefficient when a shear force is applied resulting in lateral deformation. It gives us a measure of how rigid a body is.
Diameter of Spring Wire - (Measured in Meter) - Diameter of Spring Wire is the diameter of the wire of which a spring is made.
Mean Coil Diameter of Spring - (Measured in Meter) - The Mean Coil Diameter of Spring is defined as the average of the inner and the outer diameters of a spring.
Active Coils in Spring - Active Coils in Spring is the number of coils or turns of a spring that actually contributes to the load-bearing capacity of the spring. All of the coils that aren't on the ends of a spring.
STEP 1: Convert Input(s) to Base Unit
Modulus of Rigidity of Spring Wire: 86400 Newton per Square Millimeter --> 86400000000 Pascal (Check conversion ​here)
Diameter of Spring Wire: 4 Millimeter --> 0.004 Meter (Check conversion ​here)
Mean Coil Diameter of Spring: 36 Millimeter --> 0.036 Meter (Check conversion ​here)
Active Coils in Spring: 10 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
k = G*d^4/(8*D^3*Na) --> 86400000000*0.004^4/(8*0.036^3*10)
Evaluating ... ...
k = 5925.92592592593
STEP 3: Convert Result to Output's Unit
5925.92592592593 Newton per Meter -->5.92592592592593 Newton per Millimeter (Check conversion ​here)
FINAL ANSWER
5.92592592592593 5.925926 Newton per Millimeter <-- Stiffness of Spring
