**Our Bending Stress Calculator is a cutting-edge tool designed to streamline the process of calculating bending stress, a crucial factor in the realm of structural engineering and material science. **

This powerful calculator harnesses advanced computational algorithms to provide highly accurate results, empowering professionals and enthusiasts alike to make informed decisions when dealing with bending stress analysis.

## Bending Stress Calculator

Calculate the bending stress in a beam.

Let’s consider a simple example of a rectangular beam with the following parameters:

- Bending Moment (M) = 10 kN·m
- Width (b) = 100 mm
- Height (h) = 200 mm
- Distance from the Neutral Axis (y) = 100 mm (half of the beam height)

To find the bending stress (σ), we need to calculate the Moment of Inertia (I) for a rectangular cross-section first:

```
I = (b × h^3) / 12
I = (100 mm × (200 mm)^3) / 12
I = 6.67 × 10^6 mm^4
```

Now, we can substitute the values into the bending stress formula:

```
Bending Stress (σ) = (M × y) / I
σ = (10 kN·m × 1000 N/kN × 1000 mm/m × 100 mm) / (6.67 × 10^6 mm^4)
σ = 15 MPa
```

For the given beam parameters and bending moment, the calculated bending stress is 15 MPa (megapascals).

## What is Bending Stress?

**Bending stress**, also known as **flexural stress**, is a critical concept in the field of structural engineering and material science.

It refers to the internal stresses that arise within a structural member when subjected to bending loads or moments.

These stresses are distributed across the cross-section of the member, with compression on one side and tension on the other.

Understanding and accurately calculating **bending stress** is essential for ensuring the safety and integrity of structures, as excessive bending stress can lead to deformation, cracking, or even catastrophic failure.

**Bending stress in beams solved examples**

Here are two solved examples of bending stress calculations in beams:

**Example 1:** A rectangular beam with a cross-section of 100 mm × 200 mm is subjected to a bending moment of 10 kN·m. Calculate the maximum bending stress.

**Solution:** Given:

- Bending Moment (M) = 10 kN·m
- Width (b) = 100 mm
- Height (h) = 200 mm
- Distance from the Neutral Axis (y) = 100 mm (half of the beam height)

Moment of Inertia (I) = (b × h^3) / 12 = (100 mm × (200 mm)^3) / 12 = 6.67 × 10^6 mm^4

Maximum Bending Stress (σ) = (M × y) / I σ = (10 kN·m × 1000 N/kN × 1000 mm/m × 100 mm) / (6.67 × 10^6 mm^4) σ = **15 MPa**

**Example 2:** A simply supported beam with a span length of 4 m is subjected to a concentrated load of 20 kN at the midspan. The beam has a rectangular cross-section of 150 mm × 300 mm. Calculate the maximum bending stress.

**Solution:** Given:

- Force (F) = 20 kN
- Span Length (L) = 4 m
- Width (b) = 150 mm
- Height (h) = 300 mm

Maximum Bending Moment (M) = (F × L) / 4 = (20 kN × 4 m) / 4 = 20 kN·m

Maximum Bending Stress (σ) = (3 × F × L) / (2 × b × h^2) σ = (3 × 20 kN × 4 m × 1000 N/kN × 1000 mm/m) / (2 × 150 mm × (300 mm)^2) σ = **17.78 MPa**

These examples demonstrate how to calculate the maximum bending stress in beams using the appropriate formulas and given parameters.
