# Coil Spring Force Calculator, Formula, Coil Spring Force Calculation

## Coil Spring Force Calculator:

Enter the values of Diameter of the Wire d3(m) , Radius of Coil r(m) & Shear Modulus of the Material t(pa)  to determine the value of Coil Spring Force F(Newton).

 Enter Diameter of the Wire: m Enter Radius of Coil: m Enter Shear Modulus of the Material: pa Result – Coil Spring Force: Newton

## Coil Spring Force Formula:

The coil spring force F(Newton) in Newton is equal to the 3.141 value is divided by 16times and multiply the diameter of the wire d3(m) in meter the product of divided by the radius of coil r(m) in meter into multiply the shear modulus of the material t(pa) in pascal.

The equation of coil spring force can be writtern as,

F(Newton) = pi / 16 * d3(m) / r(m) * t(pa)

Here,

F(Newton) = coil spring force in Newton

d3(m) = diameter of the wire in meter

r(m) = radius of coil in meter

t(pa) = shear modulus of the material in pascal

### Calculation for Coil Spring Force:

1)To find the coil spring force and  diameter of the wire .125m and radius of coil .50m and shear modulus of the material 1400pa.

F = pi / 16 * d3 / r  *  t

F = 3.141 / 16 * .1253 / .50 * 1400

F = 1.07N

2)To find the shear modulus of the material and coil spring force 1.07N and  diameter of the wire .125m and radius of coil .50m.
