1. What is Span of Spring?

The span of spring is basically the expanded length of spring. It represents the distance between the two support points of a leaf spring when it is in its operational position.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ l = \frac{2 \times M_b}{L} \]

Where:

Explanation: This formula calculates the span length of a leaf spring based on the bending moment and the applied load at one end of the spring.

3. Importance of Span Calculation

Details: Accurate span calculation is crucial for proper spring design, ensuring optimal performance, load distribution, and preventing premature failure in mechanical systems.

4. Using the Calculator

Tips: Enter bending moment in N·m and load in Newtons. All values must be positive numbers greater than zero for accurate calculations.

5. Frequently Asked Questions (FAQ)

Q1: What is bending moment in a spring?
A: Bending moment is the reaction induced in a structural element when an external force or moment is applied, causing the element to bend.

Q2: How is load at one end defined?
A: Load at one end is an equivalent load applied to a single point of the spring structure.

Q3: What are typical span lengths for leaf springs?
A: Span lengths vary significantly based on application, ranging from a few centimeters in small mechanisms to several meters in vehicle suspension systems.

Q4: Does this formula apply to all types of springs?
A: This specific formula is primarily used for leaf spring calculations and may not be directly applicable to other spring types like coil or torsion springs.

Q5: What factors affect spring span calculation?
A: Material properties, spring geometry, load distribution, and support conditions all influence the accurate calculation of spring span.
