1. What is Stiffness of Square Section Wire Spring?

Stiffness of Square Section Wire Spring is the resistance of the spring to deformation under an applied force. It represents how much force is required to produce a unit deflection in the spring.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ K_{sq} = \frac{G \times d^4}{44.7 \times R^3 \times N} \]

Where:

\( K_{sq} \) — Stiffness of Square Section Wire Spring (N/m)
\( G \) — Modulus of Rigidity (Pa)
\( d \) — Diameter of Spring wire (m)
\( R \) — Mean Radius of spring coil (m)
\( N \) — Number of Coils in spring

Explanation: The formula calculates the spring stiffness based on the material properties (modulus of rigidity), geometric dimensions (wire diameter and mean radius), and the number of coils.

3. Importance of Spring Stiffness Calculation

Details: Accurate spring stiffness calculation is crucial for mechanical design, vibration analysis, and ensuring proper functioning of spring-based systems in various engineering applications.

4. Using the Calculator

Tips: Enter modulus of rigidity in Pascals, diameter and mean radius in meters, and number of coils. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is modulus of rigidity?
A: Modulus of Rigidity is the measure of the rigidity of the body, given by the ratio of shear stress to shear strain. It is often denoted by G.

Q2: How does wire diameter affect spring stiffness?
A: Spring stiffness increases with the fourth power of wire diameter, making diameter the most significant factor affecting stiffness.

Q3: What is the mean radius of a spring?
A: The Mean Radius of spring coil is the average distance from the centerline of the spring wire to the axis of the spring.

Q4: How do number of coils affect stiffness?
A: Stiffness decreases as the number of coils increases, since more coils provide more flexibility.

Q5: What are typical applications of square section wire springs?
A: Square section wire springs are used in various mechanical systems where higher stiffness and compact design are required, such as in automotive suspensions and industrial machinery.
