1. What is Rectangular Steel Tubing Loading?

The load capacity of rectangular steel tubing is determined by its yield strength and section modulus. This calculation helps engineers determine the maximum load a steel tube can bear before yielding.

2. How Does the Calculator Work?

The calculator uses the basic load formula:

Where:

• \( Yield\ Strength \) — Material's yield strength in Pascals (Pa)
• \( Section\ Modulus \) — Geometric property of the cross-section in cubic meters (m³)

Explanation: The equation calculates the bending moment capacity of the steel tubing based on its material properties and cross-sectional geometry.

3. Importance of Load Calculation

Details: Accurate load calculation is crucial for structural design, ensuring safety factors are met and preventing structural failure under expected loads.

4. Using the Calculator

Tips: Enter yield strength in Pascals and section modulus in cubic meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is yield strength?
A: Yield strength is the stress at which a material begins to deform plastically. For steel, typical values range from 250-690 MPa.

Q2: How do I find section modulus?
A: Section modulus (Z) is calculated as Z = I/c, where I is the moment of inertia and c is the distance from neutral axis to outermost fiber.

Q3: What are typical section modulus values?
A: For common rectangular steel tubing, section modulus ranges from 1×10⁻⁶ to 1×10⁻³ m³ depending on dimensions.

Q4: Does this account for safety factors?
A: No, this calculates theoretical capacity. Always apply appropriate safety factors in actual design.

Q5: Can this be used for other shapes?
A: The same formula applies, but section modulus must be calculated appropriately for the specific cross-section shape.
