# Coil (Conical) Spring Force Calculator

## Introduction

Coil springs are essential mechanical components widely used in various applications to store and release energy. They come in different shapes and sizes, with conical springs being a popular choice for many engineering purposes. This Coil (Conical) Spring Force Calculator provides a simple way to determine the force exerted by a conical spring, helping engineers and designers in their mechanical projects.

## How to Use

To calculate the force exerted by a conical spring, you can follow these steps:

1. Input the Diameter of Wire (m) – This is the diameter of the wire used to create the spring.
2. Input the Mean Coil Radius (m) – The mean radius of the spring coils.
3. Input the Shear Modulus (Pa) – The shear modulus of the material used for the spring.
4. Click the “Calculate” button.

The calculator will use the provided values to determine the force exerted by the conical spring.

## Formula

The formula used to calculate the force exerted by a conical spring is as follows:

Where:

• is the Coil (Conical) Spring Force in Newtons (N).
• (pi) is a mathematical constant approximately equal to 3.14159.
• is the Diameter of Wire (m).
• is the Mean Coil Radius (m).
• is the Shear Modulus (Pa).

## Example

Suppose you have a conical spring with a wire diameter of 0.005 meters, a mean coil radius of 0.1 meters, and a shear modulus of 80,000,000 Pa.

Using the formula:

The force exerted by the conical spring is approximately 3926.99 Newtons.
