Coil springs are essential components in various industries and applications, and knowing their weight is crucial for design and engineering purposes. The Coil Spring Weight Calculator is a simple tool that helps you determine the weight of a coil spring based on key parameters. In this article, we will provide you with the code for this calculator and a guide on how to use it effectively.
Formula
The weight of a coil spring can be calculated using the following formula:
Weight (lbs) = π * (Wire Diameter / 2)^2 * Mean Diameter * Number of Coils * Coil Length * 0.000011342
Where:
- π is the mathematical constant pi (approximately 3.14159).
- Wire Diameter is the diameter of the wire used in the coil (in inches).
- Mean Diameter is the average diameter of the coil (in inches).
- Number of Coils is the total number of coils in the spring.
- Coil Length is the length of the coil spring (in inches).
How to Use
Using the Coil Spring Weight Calculator is easy and straightforward:
- Enter the Number of Coils in the appropriate field.
- Input the Wire Diameter (in inches).
- Provide the Mean Diameter (in inches).
- Specify the Coil Length (in inches).
- Click the “Calculate” button.
- The result will appear below, displaying the weight of the coil spring in pounds (lbs).
Example
Let’s consider an example to better understand how the Coil Spring Weight Calculator works:
- Number of Coils: 10
- Wire Diameter: 0.2 inches
- Mean Diameter: 2 inches
- Coil Length: 8 inches
After entering these values and clicking “Calculate,” the calculator will display the result:
Result: 8.98 lbs
This means that a coil spring with the given parameters has an approximate weight of 8.98 pounds.
