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

Inside Diameter of Spring Coil given Mean Coil Diameter Formula

Inner Diameter of Spring Coil = 2*Mean Coil Diameter of Spring-Outer Diameter of Spring Coil
D_i = 2*D-D_o

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.
