STEP 1: Convert Input(s) to Base Unit

Axial Force on Valve Spring: 340 Newton --> 340 Newton No Conversion Required
Active Coils in Valve Spring: 12 --> No Conversion Required
Mean Coil Diameter of Valve Spring: 46 Millimeter --> 0.046 Meter (Check conversion here)
Modulus of Rigidity of Valve Spring: 98900 Newton per Square Millimeter --> 98900000000 Pascal (Check conversion here)
Wire Diameter of Valve Spring: 5.5 Millimeter --> 0.0055 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

x = (8*P*N*D^3)/(G*d_w^4) --> (8*340*12*0.046^3)/(98900000000*0.0055^4)

Evaluating ... ...

x = 0.0351056158001661

STEP 3: Convert Result to Output's Unit

0.0351056158001661 Meter -->35.1056158001661 Millimeter (Check conversion here)

FINAL ANSWER

35.1056158001661 ≈ 35.10562 Millimeter <-- Maximum Compression in Valve Spring

Cold drawn steel wire for spring manufacturing

Cold-formed steel parts and products are well known for having greater tensile strength and tolerance to stress and temperature – not to mention the surface finish. Cold drawing is a type of work hardening that affects the material's basic crystalline structure which changes its properties. Talented spring manufacturers apply a variety of techniques to create wire forms and springs such as tension springs and die springs, with different qualities and capabilities for different applications.
