1. What is Stiffness of Helical Spring?

Stiffness of Helical Spring is a measure of the resistance offered by an elastic body to deformation. Every object in this universe has some stiffness. In the context of springs, it represents how much force is required to produce a unit deflection.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( k \) — Stiffness of Helical Spring (N/m)
• \( P \) — Axial Load (N)
• \( \delta \) — Deflection of Spring (m)

Explanation: The stiffness is calculated by dividing the axial load by the resulting deflection of the spring.

3. Importance of Spring Stiffness Calculation

Details: Calculating spring stiffness is crucial for designing mechanical systems, ensuring proper functionality, and predicting the behavior of springs under various loads in engineering applications.

4. Using the Calculator

Tips: Enter axial load in Newtons (N) and deflection in meters (m). All values must be valid (load > 0, deflection > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is the unit of spring stiffness?
A: Spring stiffness is measured in Newtons per meter (N/m) in the SI system.

Q2: How does spring material affect stiffness?
A: The material's modulus of elasticity directly affects spring stiffness. Higher modulus materials result in stiffer springs.

Q3: What factors influence helical spring stiffness?
A: Spring stiffness depends on wire diameter, coil diameter, number of coils, and material properties.

Q4: Is this formula applicable to all types of springs?
A: This specific formula k = P/δ is generally applicable for linear springs where deflection is proportional to load.

Q5: How does temperature affect spring stiffness?
A: Temperature changes can affect the material properties of the spring, potentially altering its stiffness, especially with significant temperature variations.
