1. What is Bending Stress in Column?

Bending Stress in Column is the normal stress that is induced at a point in a body subjected to loads that cause it to bend. It occurs when an eccentric load is applied to a column, creating both direct stress and bending stress.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \sigma_b \) — Bending Stress in Column (Pa)
• \( e_{load} \) — Eccentricity of Loading (m)
• \( P \) — Eccentric load on column (N)
• \( S \) — Section Modulus (m³)

Explanation: The formula calculates the bending stress caused by an eccentric load applied at a certain distance from the centroid of the column section.

3. Importance of Bending Stress Calculation

Details: Accurate bending stress calculation is crucial for structural design and analysis, ensuring that columns can safely withstand combined axial and bending loads without failure.

4. Using the Calculator

Tips: Enter eccentricity of loading in meters, eccentric load in Newtons, and section modulus in cubic meters. All values must be positive and valid.

5. Frequently Asked Questions (FAQ)

Q1: What is eccentricity of loading?
A: Eccentricity of Loading is the distance between the actual line of action of loads and the line of action that would produce a uniform stress over the cross section.

Q2: What is section modulus?
A: Section Modulus is a geometric property for a given cross-section used in the design of beams or flexural members.

Q3: When does bending stress occur in columns?
A: Bending stress occurs when loads are applied eccentrically to the column's centroid, creating a bending moment in addition to axial compression.

Q4: How does bending stress affect column design?
A: Bending stress must be considered in column design to ensure the combined stresses (axial + bending) do not exceed the material's allowable stress limits.

Q5: What units should be used for input values?
A: Use meters for eccentricity, Newtons for load, and cubic meters for section modulus to get results in Pascals.
