1. What is an Angle Iron Span Calculator?

Definition: This calculator estimates the maximum span length for angle iron based on its moment of inertia, yield strength, width, and applied load.

Purpose: It helps engineers and construction professionals determine safe span lengths for angle iron used in structural applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( I \) — Moment of inertia (m⁴)
• \( \text{Yield} \) — Yield strength of material (Pa)
• \( \text{Width} \) — Width of angle iron (m)
• \( \text{Load} \) — Applied load (N)

Explanation: The formula calculates the maximum unsupported length an angle iron can span before yielding under the given load.

3. Importance of Angle Iron Span Calculation

Details: Proper span calculation ensures structural integrity, prevents deformation, and maintains safety standards in construction projects.

4. Using the Calculator

Tips: Enter the moment of inertia, yield strength (default 250 MPa for mild steel), width (default 0.05 m), and load (default 1000 N). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is moment of inertia (I) for angle iron?
A: It's a geometric property that depends on the angle's dimensions. Standard values can be found in engineering tables or calculated using CAD software.

Q2: What's a typical yield strength for angle iron?
A: Mild steel typically has 250 MPa yield strength, while high-strength steel can have 350 MPa or more.

Q3: Does this account for dynamic loads or safety factors?
A: No, this is a basic calculation. For real-world applications, apply appropriate safety factors based on local building codes.

Q4: How do I find the load value?
A: Calculate the total expected load (dead load + live load) that will be applied to the angle iron.

Q5: Does this work for other steel shapes?
A: The formula is specific to angle iron. Other shapes (I-beams, channels) require different calculations.
