Mean Coil Diameter given Spring Index Solution

STEP 0: Pre-Calculation Summary
Formula Used
Mean Coil Diameter of Spring = Spring Index*Diameter of spring wire
D = C*d
This formula uses 3 Variables
Variables Used
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.
Spring Index - Spring Index is defined as the ratio of mean coil diameter of the spring to the diameter of the spring Wire.
Diameter of spring wire - (Measured in Meter) - Diameter of spring wire is the diameter of the wire of which a spring is made.
STEP 1: Convert Input(s) to Base Unit
Spring Index: 9 --> No Conversion Required
Diameter of spring wire: 4 Millimeter --> 0.004 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
D = C*d --> 9*0.004
Evaluating ... ...
D = 0.036
STEP 3: Convert Result to Output's Unit
0.036 Meter -->36 Millimeter (Check conversion here)
FINAL ANSWER
36 Millimeter <-- Mean Coil Diameter of Spring
(Calculation completed in 00.020 seconds)

9 Geometry of Helical Springs Calculators

Diameter of Spring Wire from Load Stress Equation
Go Diameter of spring wire = sqrt(Wahl Factor of Spring*(8*Axial Spring Force*Spring Index)/(pi*Shear Stress in Spring))
Spring Index given Shear stress in Spring
Go Spring Index = Shear Stress in Spring*(pi*Diameter of spring wire^2)/(Wahl Factor of Spring*8*Axial Spring Force)
Mean Coil Diameter of Spring
Go Mean Coil Diameter of Spring = (Outer Diameter of Spring Coil+Inner Diameter of Spring Coil)/2
Inside Diameter of Spring Coil given Mean Coil Diameter
Go Inner Diameter of Spring Coil = 2*Mean Coil Diameter of Spring-Outer Diameter of Spring Coil
Outside Diameter of Spring given Mean Coil Diameter
Go Outer Diameter of Spring Coil = 2*Mean Coil Diameter of Spring-Inner Diameter of Spring Coil
Total Number of Coils given Solid Length of Spring
Go Total Coils in Spring = Solid Length of Spring/Diameter of spring wire
Diameter of Spring Wire given Spring Index
Go Diameter of spring wire = Mean Coil Diameter of Spring/Spring Index
Mean Coil Diameter given Spring Index
Go Mean Coil Diameter of Spring = Spring Index*Diameter of spring wire
Spring Index
Go Spring Index = Mean Coil Diameter of Spring/Diameter of spring wire

Mean Coil Diameter given Spring Index Formula

Mean Coil Diameter of Spring = Spring Index*Diameter of spring wire
D = C*d

Define a Spring?

A spring is an elastic object that stores mechanical energy. Springs are typically made of spring steel. There are many spring designs. In everyday use, the term often refers to coil springs. The rate or spring constant of a spring is the change in the force it exerts, divided by the change in deflection of the spring.
